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
Answer:
the answer would be 39 nickels and 17 quarters
Step-by-step explanation:
i did guess and check so i will just give the answer and the work for it
4.25/.25=17 quarters
56-17=39
39*.05=1.95
1.95+4.25=6.20
370.75 ~ 371
Example:
