Question

A piggy bank contains nickels and dimes. There are 160 total coins valuing $10.50. Think about a system of equations that can be used to represent the number of nickels and dimes and then think through using substitution to solve the system of equations. How many nickels are in the piggy ban

Answer 1

Lets say nickles are X and Y are dimes

Answer 2

since both nickles and dimes add up to 160 in total (forget about the monetary value) you can set up the first equation 160=x+y

Answer 3

since a dime is worth .10 and a nickle is .05 you can set up the equation .10y+.05x10.50
