by ADMIN 46 views

Hey guys! Ever wondered how much money you have in your wallet or purse? Or how to pay the exact amount for something you want to buy? Let's dive into a fun math problem about Aulia, who has a bunch of money in her bag and wants to buy a doll. We'll figure out how much money she has and how she can pay the exact amount for her toy. Get ready for some exciting calculations!

How Much Money Does Aulia Have?

So, let’s start by figuring out exactly how much cash Aulia is carrying around. This is a great way to practice our addition and multiplication skills, and it's super practical for real life too. Imagine you're in Aulia's shoes – you need to know how much you've got before you can start spending, right?

  • The Big One: Rp100,000 Note

    Aulia has one crisp Rp100,000 note. That's the biggest bill in her bag, and it forms the foundation of her total. We can write this down as:

    1 x Rp100,000 = Rp100,000

    This single note already gives us a significant chunk of her total. But there's more to come!

  • The Rp10,000 Bills

    Next up, Aulia has four Rp10,000 bills. These are like the supporting cast, adding a substantial amount to her stash. To calculate the total from these, we multiply the number of bills by their value:

    4 x Rp10,000 = Rp40,000

    Adding this to our previous total, we’re starting to see Aulia’s wealth grow.

  • The Rp5,000 Bills

    Aulia also has three Rp5,000 bills. These are the mid-range bills, contributing a decent amount to her overall total. Let's calculate their worth:

    3 x Rp5,000 = Rp15,000

    Every little bit counts, and these Rp5,000 notes are definitely helping!

  • The Rp1,000 Bills

    Now, we get to the five Rp1,000 bills. These might seem small individually, but they add up. Let's see how much they contribute:

    5 x Rp1,000 = Rp5,000

    These smaller bills are great for making exact change and come in handy for smaller purchases.

  • The Rp100 Coins

    Finally, we have the eight Rp100 coins. These are the smallest denominations, but they still matter! Let's calculate their total value:

    8 x Rp100 = Rp800

    Okay, so now we have all the individual amounts. The next step is to add them all together to find Aulia’s grand total.

    Rp100,000 (from the Rp100,000 note) + Rp40,000 (from the Rp10,000 bills) + Rp15,000 (from the Rp5,000 bills) + Rp5,000 (from the Rp1,000 bills) + Rp800 (from the Rp100 coins)

    Let's break it down step by step:

    • Rp100,000 + Rp40,000 = Rp140,000
    • Rp140,000 + Rp15,000 = Rp155,000
    • Rp155,000 + Rp5,000 = Rp160,000
    • Rp160,000 + Rp800 = Rp160,800

    So, Aulia has a grand total of Rp160,800 in her bag! That’s quite a bit of money. Now we know how much she has to work with when she goes to buy her doll.

Buying the Doll: Paying Exactly Rp38,500

Okay, so Aulia has Rp160,800, and she wants to buy a doll that costs Rp38,500. The challenge now is to figure out how she can pay the exact amount. This is a fun puzzle that involves choosing the right combination of bills and coins. Paying the exact amount is super useful because it means you don't get a ton of change back, which can be annoying to carry around.

Let’s break down how Aulia can do this. We need to find a combination of her Rp100,000, Rp10,000, Rp5,000, Rp1,000 bills, and Rp100 coins that adds up to Rp38,500.

Method 1: Using a Combination of Bills

  • One Rp10,000 Bill: This gets us to Rp10,000.
  • Five Rp5,000 Bills: This adds another Rp25,000 (5 x Rp5,000), bringing our total to Rp35,000.
  • Three Rp1,000 Bills: This gives us an additional Rp3,000 (3 x Rp1,000), making the total Rp38,000.
  • Five Rp100 Coins: This final touch adds Rp500 (5 x Rp100), completing the Rp38,500.

So, Aulia can pay with one Rp10,000 bill, five Rp5,000 bills, three Rp1,000 bills, and five Rp100 coins. Let's write this out as an equation to make it super clear:

(1 x Rp10,000) + (5 x Rp5,000) + (3 x Rp1,000) + (5 x Rp100) = Rp38,500

Method 2: Another Way to Pay

There’s often more than one way to solve a math problem, and paying for something is no different! Let’s see if we can find another combination of bills and coins that Aulia can use.

  • Three Rp10,000 Bills: This immediately gets us to Rp30,000 (3 x Rp10,000).
  • One Rp5,000 Bill: This adds another Rp5,000, bringing the total to Rp35,000.
  • Three Rp1,000 Bills: This contributes Rp3,000 (3 x Rp1,000), making the total Rp38,000.
  • Five Rp100 Coins: Finally, we add Rp500 (5 x Rp100) to reach Rp38,500.

So, in this method, Aulia can use three Rp10,000 bills, one Rp5,000 bill, three Rp1,000 bills, and five Rp100 coins. Let's write this out as an equation as well:

(3 x Rp10,000) + (1 x Rp5,000) + (3 x Rp1,000) + (5 x Rp100) = Rp38,500

Why Are There Multiple Ways to Pay?
