Answer:

9 nickels

Step-by-step explanation:

Set the number of pennies as x. The number of nickels would be 31 - x.

The pennies are worth x cents and the nickels are worth 5 * (31 - x), or 155-5x.

We are given that he has 67 cents, so:

x + 155 - 5x = 67

Solve.

-4x = 67 - 155 = -88

x = 22

Nickels are 31 - x, so the number of nickels he has is 9.

I hope this helps!
