Question

Karen has 5 more quarters than dimes. She has $3.70. How many quarters and dimes she have?

Answer 1

A dime is 10% of a dollar = 10/100 x 100 cent = 10 cents

A quater is 25% of a dollar = 25/100 x 100 cent = 25 cents

Since Karen has 5 more quaters than dimes

let quaters = q

let dimes = d

Then Karen has 5q : d = $ 3.70

$ 3.70 = 3.70 x 100 cents = 370 cents
