Jennifer have 8 quarters, 12 dimes and 36 nickels.
Step-by-step explanation:
Given,
Worth of coins = $5.00 = 5*100 = 500 cents
One quarter = 25 cents
One dime = 10 cents
One nickel = 5 cents
Let,
x = number of quarters
y = number of dimes
z = number of nickels
According to given statement;
25x+10y+5z=500 Eqn 1
y = x+4 Eqn 2
z = 3y
z = 3(x+4) => z = 3x+12 Eqn 3
Putting value of y and z from Eqn 2 and 3 in Eqn 1

Dividing both sides by 50

Putting x = 8 in Eqn 2

Putting x=8 in Eqn 3

Jennifer have 8 quarters, 12 dimes and 36 nickels.
