Karli Cook · Answer 1

1 nickel = $0.05

1 dime = $0.10

n - number of nickels

7n - number of dimes

A equation:

0.05n + 0.1 · 7n = 5.25

0.05n + 0.7n = 5.25

0.75n = 5.25 |divide both sides by 0.75

n = 7

Answer: He have 7 nickels.

Belinda Mercer · Answer 2

Let dimes be represented by d and n for nickels;

1 dime = 0.1 dollars

1 nickel=0.05 dollars

0.1d+0.05n=5.25

d=7n

so,

0.1 (7n) + 0.05n=5.25

0.7n+0.05n=5.25

0.75n=5.25

n=7

There are 7 nickels and 49 dimes
