Kameron has a combination of quarters and nickles in his wallet. the number of nickels is three times the number of quarters he has. if the total value of the coins is two dollars how many quarters does kameron have in his wallet?

Kameron has 5 quarters in his wallet

Step-by-step explanation:

Let

x> the number of nickels

y> the number of quarters

remember that

1 nickel=$0.05

1 quarter=$0.25

we know that

x=3y > equation A

0.05x+0.25y=2

Multiply by 100 both sides

5x+25y=200

Simplify

x+5y=40 > equation B

Substitute equation A in equation B

(3y)+5y=40

8y=40

y=5 quarters

x=3(5)=15 nickels

i think its doubled. let me know
