Prince started with $0 in his savings account and is saving $15 per week. Chastity has $40 in her savings account and is saving $5 per week. Write an equation that can be used to determine the number of weeks, w, that Jeremiah and Tatiana will have the same amount of money in their savings account.

The equation for this problem would be 15x=40+5x. First you would subtract 5x from both sides. The new equation is 15x-5x=40. You then subtract 5x from 15x which gets you 10x=40. You would then divide 10 from each side and get x=4
