Question

Connor has $9.00 in dimes and quarters. If he has twice as many quaters as dimes, how many of each coin does he have?

Answer 1

So since we have a relationship between quarters and dimes, let's use dimes=d

`0.1d+(0.25)2d=9`
This says that dimes(0.1 dollars) and twice as many dimes(quarters so 0.25) is 9 dollars. So it is

`0.1d+0.5d=9`
Combining we get

`0.6d = 9`
Dividing by 0.6 we get

`d=15`
Since there are twice as many quarters as dimes, the answer is 15 dimes and 30 quarters.

Answer 2

Hi There!

Answer:

30 quaters.

15 dimes.

Explanation:

Quarter = $0.25

Dime = $0.10

Quarters: 0.25 * 30 = $7.50

Dimes: 0.10 * 15 = $1.50

Check: 7.50 + 1.50 = $9

Hope This Helps :)
