Fred has a bag of coin with only nickels and quarters. He got $20 by
Sedbober [7]

Answer:

75 quarters 25 nickels

Step-by-step explanation:

q=quarters n=nickels

q+n=100   n=100-q

0.25q +0.05(100-q)=20

From now I will multiply  by 100 to avoid decimals

25q + 5(100-q)=2000

20q=1500

q=75       n=25

75*0.25= 18.75

25*0.05=1.25

18.75+1.25=20
