Problema Solution
A woodworker builds a cabinet in 20 hours. The cabinet is sold for $500. Write and solve an inequality that represents the hourly wage the store can pay the woodworker and still make a profit of $100.
Answer provided by our tutors
let x = the hourly wage of the worker
the total money paid to the worker is: 20*x
the profit is: 500 - 20*x
the profit needs to be at least $100
500 - 20*x >= 100
by solving we find
x <= 20
