Question

Emily has pennies and five dollar bills in her pocket. The number of pennies is eight less than three times the number of five dollar bills. Let f represent the number of five dollar bills. Write an expression for the number of pennies

Answer 1

3f - 8 = number of pennies

Explanation:

3f - 8 = number of pennies

Answer 2

p = 3*f - 8

Explanation:

Let f represent the number of five dollar bills and p the number of pennies.

The expression "The number of pennies is" is equivalent to "p =";

"three times the number of five dollar bills" is equivalent to "3*f"

"eight less than three times the number of five dollar bills" is equivalent to "3*f - 8"

Then the expression is p = 3*f - 8
