How to find the number of pennies and nickels?

Autumn has $.64 worth of pennies and nickels. She has a total of 20 pennies and nickels all together.

Therefore,

let

x = number of pennies

y = number of nickels

Hence,

x + y = 20

0.01x + 0.05y = 0.64

Multiply equation(i) by 0.01

0.01x + 0.01y = 0.2

0.01x + 0.05y = 0.64

0.04y = 0.44

y = 0.44 / 0.04

y = 11

Therefore,

x = 20 - 11

x = 9

Therefore, the number of pennies and nickels are 9 and 11 respectively.
