Hi Renee, I am going to suggest two ways to solve this problem. Method 1:
Solve the problem this way and then proceed. Method 1 ignores the instruction to "Write an equation and solve" but I like method 1 better than the algebraic, method 2 technique. Method 2:
The two methods are really the same, one uses a variable $s$ and the other just uses logic. Penny | |||||||||||||||
