If devin has 3 times as many nickels as quarters and they have a combined value of 200 cents how many of each coin does he have

Answers

Devin has 15 nickel coins and 5 quarter coins.

Step-by-step explanation:

Total worth = 200 cents

1 nickel = 5 cents

1 quarter = 25 cents

Let,

Nickels = x

Quarters = y

According to given statement;

5x+25y=200    Eqn 1

x = 3y    Eqn 2

Putting x=3y in Eqn 1

5(3y)+25y=200\n15y+25y=200\n40y=200

Dividing both sides by 40

(40y)/(40)=(200)/(40)\ny=5

Putting y=5 in Eqn 2

x=3(5)\nx=15

Devin has 15 nickel coins and 5 quarter coins.
