Problema Solution
A baseball cost $8.47 less than a basketball. If together they cost $19.11, how much does the basketball cost?
Answer provided by our tutors
let
x = the cost of baseball
y = the cost of basketball
A baseball cost $8.47 less than a basketball:
x = y - 8.47
together they cost $19.11:
x + y = 19.11
by solving the system of equations:
x = y - 8.47
x + y = 19.11
we find:
x = $5.32
y = $13.79
