Question

you have at least $60 in change in your piggy bank, consisting of quarters and pennies. Write an inequality that shows the different number of coins in your piggy bank.

Answer 1

Let x and y be your variables, where:

x = number of quarters
y = number of pennies

The total value of your money is $60, so set the right side of the equation equal to that. Then, use the value of the other coins as their respective coefficients.

0.25x + 0.01y = 60
