Question

I NEED HELP!!!! Gavin and Percy are band students. They are tested on, and there are a certain number of scales they need to pass. Gavin has passed 11 scales, whereas Percy has passed 8 scales. Gavin wants to pass 2 scales a week, and Percy wants to pass 5 per week. At some point, they will pass the same number of scales. A. How long will it take them to pass the same number of scales? B. How many scales will that be?

Answer 1

Below

Explanation:

G = 11 + 2w <===== 11 passed + 2 more per week

P = 8 + 5w <====== 8 passed and 5 more per week

When are they equal ?

Equate G and P equations:

11+ 2w = 8 + 5w

3 = 3w

w =1 after ONE week they will have the same G = 13 = P
