Malikah saves all of his pennies and nickels. After a year he has a total of 520 coins After counted the coins he had a total of $14.72 How many nickels does he hove?

238 nickels

282 pennies

Step-by-step explanation:

N =Nickels    

P= Pennies

20 nickels = 1 dollar

100 pennies = 1 dollar

N+P = 520

P=( 520-N)

0.05(N) +0.01(520-N) = $14.72

Multiply by 100 to avoid decimals:

5 N +1(520-N) = 1,472

5N +520 -N = 1,472

4N = 952

N = 238  (238/20 = 11.9)  $11.9

520-238 = 282 pennies (=$ 2.82)

238 + 282 = 520

$11.9 + $2.82 = $ 14.72

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
