Question

Debbie has 8 quarters and 24 pennies in her piggy bank. She has n times as many pennies as quarters. Which equation can be used to find n

Answer 1

8n = 24

Explanation:

Answer 2

The equation that can be used to solve n is 8n = 24

Explanation:

Given

Q = Quarter = 8

P = Penny = 24

Condition

She has n times as many pennies as quarters.

Required

Equation to find n

The statement "She has n times as many pennies as quarters." means that the relationship between penny and quartets is

Penny = quarter * n

P = Q * n

P = nQ

By substituton (P = 24 and Q = 8)

P = nQ becomes

24 = n * 8

24 = 8n

8n = 24

Hence, the equation that can be used to solve n is 8n = 24

Solving further

Multiply both sides by ⅛

8n = 24 becomes

8n * ⅛ = 24 * ⅛

n = 3
