Hi There!
Answer:
30 quaters.
15 dimes.
Step-by-step 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 :)
So since we have a relationship between quarters and dimes, let's use dimes=d
[tex]0.1d+(0.25)2d=9[/tex]
This says that dimes(0.1 dollars) and twice as many dimes(quarters so 0.25) is 9 dollars. So it is
[tex]0.1d+0.5d=9[/tex]
Combining we get
[tex]0.6d = 9[/tex]
Dividing by 0.6 we get
[tex]d=15[/tex]
Since there are twice as many quarters as dimes, the answer is 15 dimes and 30 quarters.
[tex]0.1d+(0.25)2d=9[/tex]
