Question

Patty had four times as many quarters as nickels. She had $12.60 in all. How many nickels and

she have?

Answer 1

Hi,

Explanation:

Let say n the number of nickels

4*n the number of quaters.

Let's calculate in cents:

n*5+4*n*25=1260

5n+100n=1260

105*n=1260

n=12 (number of nickels)

4n=48 (number of quaters)

Proof: 12*5+48*25=1260

Answer is equation B
