Question

Your group has 10 pennies and 10 nickels. Use these pennies and nickels to solve the following problems.

Answer 1

Answer:

p=8

n=3

Step-by-step explanation:

let number of pennies=p

number of nickels=n

p+n=11

n=11-p

1*p+5*n=23

p+5(11-p)=23

p+55-5p=23

55-4p=23

4p=55-23=32

p=32/4=8

n=11-8=3
