Question

I have 35 quarters and dimes in

my pocket. How many of each do I have if I have $5.45??
HELP Me pls

Answer 1

13 Quarters, 22 Dimes

Explanation:

.10d + .25q = 5.45

.10 (35 - q) + .25q = 5.45

3.5 - 10q + .25q = 5.45

.25q - .10q = 5.45 - 3.5

.15q = 1.95

q = 13

Plug the value of q to solve for d, or the number of dimes.

d = 35 - q

d = 35 - 13

d = 22
