Equation and no solution

Question

Jeremy is looking at two different lawncare companies to weed and mulch his garden. Greenscape lawn care charges $100 for the mulch,plus $12 per hour for the labor. DJ’s lawncare charges $23 per hour, which includes the price for the mulch. What is maximum number of hours for which DJ’s lawncare is a better deal?

Answer 1

let t = No. hrs.

G's cost is $12t + $100

DJ's cost is $23t.

Set up an inequality and solve for t: 12t + 100 > 23t
