Answer :
Answer: 17 dimes
1. There are 100 coins in total.
+ = 100
d+q=100 (Equation 1)
2. The total value of the coins is $22.45. Since each dime is worth $0.10 and each quarter is worth $0.25, the total value can be expressed as:
10 + 0.25 = 22.45
0.10d+0.25q=22.45 (Equation 2)
then solve the equations
