Question

Henry’s Moving Company charges an initial fee of $50 plus $20 per hour (H). The total cost (T) can be determined using the equation: t=50+20H

Jones Moving Company charges an initial fee of $100 plus $10 per hour (H). Which
company would be cheapest if you were going to hire them for 5 hours?

Answer 1

C=50+20h

Explanation:

The $50 dollars in this equation is a flat fee, no variable to it. It doesn't increase or decrease depending on the number of hours. The $20 dollars is dependent on the number of hours the plumber works. If the plumber works 2 hours they get $40 dollars, the amount the plumber receives depends on the hours worked. The h in the equation is a placeholder for hours worked. To solve the equation just replace h with the hours worked and solve to get the answer.
