How much did sally save?

Question

Sally has 25 more dimes than nickles. She saved 6 times more dimes than nickels. How much did she save.

Answer 1

Let n = number of nickles

d = number of dimes

then,

d = n + 25

d = 6n

So,

6n = n + 25

5n = 25

n = 5 (number of nickles)

so d = 30 (number of dimes)
