Answer 1

Answer and Step-by-step explanation:

So, lets write down the information that we have.

Tina:

Box Jumps: 500

Pushups: 350

Sit-ups: 700

Ben:

Box Jumps and Sit-ups:
`(3)/(4)` × (500 + 700)

Pushups: 1.5 × 350

Let's calculate Ben's exercises.

Pushups = 525

Box Jumps + Sit-ups = 900

Look back, and you can see that we can distribute the 3/4 to the numbers, instead of adding the multiplying.

(
`(3)/(4)` × 500) = 375

(
`(3)/(4)` × 700) = 525

So, Ben did:

Box Jumps = 375

Pushups = 525

Sit-ups = 525
