Question

When courtney collected her change she realized she had five times as many dimes as quarters. her dimes and quarters totaled $5.25. how many quarters did she have?

Answer 1

Dimes (0.10): 5Q

Quarters (0.25): Q

Dimes + Quarters = Total

0.10(5Q) + 0.25(Q) = 5.25

0.50Q + 0.25Q = 5.25

0.75Q = 5.25

`(0.75Q)/(0.75)` =
`(5.25)/(0.75)`

Q = 7

Answer: 7 quarters
