2 answers:
Answer: 326 dimes
Step-by-step explanation:
q + 0.05(197) = 42.45
q + 9.85 = 42.45
q = 42.45 - 9.85
q = $32.6
32.6 / 0.10 = 326
Answer:
326 dimes.
Step-by-step explanation:
total value = 197 * value of one nickel
total value = 197 * 0.05
total value = 9.85
Value of dimes = 42.45 - 9.85
Value of dimes = 32.60
1 dollar contains 10 dimes
32.60 dollars contain x dimes
1/32.60 = 10/x Cross multiply
x = 32.60 * 10
x = 326 Dimes
