Question

Rhonda has $1.35 in nickels and dimes in her

pocket. If she has six more dimes than nickels,
which equation can be used to determine x, the
number of nickels she has?

Answer 1

7 nickels

Explanation:

let x = number of nickels

If she has six more dimes than nickels, we can make an expression

x + 6

1 dime = 10 cents

1 nickel = 5 cents

10x + 5(x+6) = 135

10x + 5x + 30 = 135

15x = 135 - 30

15x = 105

x = 7
