Question

Use the five-step thinking plan to help you solve this problem.



Jill has $8.75. Jack has three times as much as Jill, but he spent $5.00 to buy a book. How much money does Jack have?

Answer 1

Step 1: Understand the problem
- Jill has $8.75.
- Jack has three times as much money as Jill.
- Jack spent $5.00 to buy a book.
- We need to find out how much money Jack has.

Step 2: Devise a plan
- Since Jill has $8.75 and Jack has three times as much money, we need to multiply $8.75 by 3.
- After that, we need to subtract $5.00 from the result to account for the book purchase.

Step 3: Carry out the plan
- Multiply $8.75 by 3: $8.75 x 3 = $<<8.75*3=26.25>>26.25
- Subtract $5.00: $26.25 - $5.00 = $<<26.25-5=21.25>>21.25

Step 4: Check the solution
- To check if our solution is correct, we can verify that Jack's money is indeed three times Jill's original amount minus the book expenditure.
- Three times $8.75 is $26.25, and subtracting $5.00 gives us $21.25.

Step 5: Reflect on the solution
- Jill has $8.75.
- After spending $5.00, Jack has $21.25.
