Question

Aliyah has $1.03 in dimes and pennies. The number of pennies is 4 more than the number of dimes. Determine the number of dimes.

Answer 1

Let n be the number of dimes one has

(n + 4) * 1 + n * 10 = 103 to get current price

11 n + 4 = 103

n = 9 where n is the number of dimes

Check:

9 * 10 = 90

13 * 1 = 13

Total = 103
