how many more nickels than quarters does he have?
have?

10

Step-by-step explanation:

20 quarters: $5 and

10 nickels: 50 cents

20-10=10

20 quarters ($5) and 10 nickels ($0.50)

Step-by-step explanation:

Q+ N = 30

Q = 30-N

0.5N + 0.25(30-N) = 5.50

0.5N + 7.50-0.25N = 5.50

-0.20N = -2

N=10            Q=30-N   Q=30-10       Q=20

10*0.5 = 0.50

20*0.25 = 5

5 + 0.5 =  $5.50

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
