Question

A piggy bank contains dimes and nickels that are worth a total of $42.45. If there are 197 nickels, how

Answer 1

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 2

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
