Problema Solution
1) Jake's mom gives him $4.00 to spend on candy a the store. He bought 8 pieces of candy. If jawbreakers cost $.40 each and lollipops cost $.60 each, how much of each candy did he buy, assuming he spent all of his money?
Answer provided by our tutors
let
x = the number of jawbreakers
y = the number of lollipops
He bought 8 pieces of candy:
x + y = 8
Jake's mom gives him $4.00 to spend on candy a the store and he spent all of his money:
0.40x + 0.60y = 4.00
by solving the system of equations:
x + y = 8
0.40x + 0.60y = 4.00
we find:
x = 4 jawbreakers
y = 4 lollipops
