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

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

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
