Problema Solution
Jeremy is looking at two different lawncare companies to weed and mulch his flower beds. Greenscape Lawncare offers to charge $100 for the mulch plus $12 per hr for the labor. D&J Landscape offers to charge $23 per hr for the job including the mulch. What is the minimum number of hours the job could be for D&J Landscape to have the better deal?
Answer provided by our tutors
100 + 12x = 23x (where x is the number of hours) (minus 12x to both sides)
100 = 11x (divide by 11 to both sides)
x = 9.09 hours. The D&J Landscape will have to spend less than 9.09 hours in order to be more cost effective
Proof:
3 hours
D&J = $69 Greenscape Lawncare = $136
15 hours
D&J = $345 Greenscape Lawncare = $280
9.09 hours
D&J = $209.07 ~ Greenscape Lawncare = $209.08
