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