Answer 1

The answer will be 580

Answer 2

Answer:

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
