Solution

A ratio of pennies to nickels of 5 to 3 means that we can write the number of pennies and nickels in the form

number of pennies = 5x and number of nickels = 3x

But we know the number of nickels, 30. Hence

3x = 30

Solve for x

x = 10

The total number of coins is given by

5x + 3x = 8x = 8 × 10 = 80
