Question

You and your friend are saving for a vacation. You start with the same amount and save for the same number of weeks. You save $75 per week, and your friend saves $50 per week. When vacation time comes, you have $950, and your friend has $800. How much did you start with, and for how many weeks did you save?
A. $500, 6 weeks
B. $600, 4 weeks
C. $650, 3 weeks
D. $700, 2 weeks

Answer 1

The answer would be A. If you plug in the numbers to this equation:

800=50x+B and 950=75x+B, where B is the amount you started and X is the number of weeks you saved your money, you would get that the number of weeks you saved your money is 6 and the amount you started out with is $500

75(6)+500=950

50(6)+500=800
