Answer: To determine Rocco´s weight jake must use this expression

p = 55 - 0.5 w

Step-by-step explanation:

Hi to solve this problem we have to analyze the information given:

Rocco´s initial weight: 55 pounds

Pounds lost per week: 0.5 pounds

So, we have to write an equation where p is Rocco's weight after w weeks.

Each week Rocco will lose 0.5 pounds so the expression is 0.5w, where w is the number of weeks.

Mathematically speaking:

p = 55 - 0.5 w

By replacing w by the number of weeks, Jake will obtain Rocco´s weight.

For example, if the number of weeks is 20:

p= 55-0.5x 10

p= 55 - 20

p= 35

After 20 weeks Rocco will lose 10 pounds.
