Question

Sally gave her brother $3.95 in quarters and dimes if the number of quarters is 6 mores than the number of dimes how many quarters did sally give her brother

Answer 1

13 quarters

Explanation:

If we add 6 dimes, the total becomes 4.55, and there will be an equal number of quarters and dimes. That is, the money can be divided into coin pairs (quarter + dime) that are worth 0.35.

4.55/0.35 = 13

such pairs can be formed.

Sally gave her brother 13 quarters.
