Answer:
There are 15 dimes and 13 quarters.
Step-by-step explanation:
Let d = number of dimes and q = number of quarters.
The number of dimes and quarters is 28:
d + q = 28
Solve for d:
d = 28 - q
Total dollar amount of dimes and quarters is $4.75 or 475 cents:
10d + 25q = 475
Substitute:
10(28 - q) + 25q = 475
280 - 10q + 25q = 475
15q = 475 - 280
15q = 195
q = 195/15
q = 13 quarters
Solve for d:
d = 28 - q
d = 28 - 13 = 15 dimes
Proof:
10d + 25q = 475
10(15) + 25(13) = 475
150 + 325 = 475
475 = 475
