answer:

7 hours

180 dollars

Step-by-step explanation:

If we let the total amount payed to be y. and hours to be x, then our equation becomes, y = 5x+60. to solve for the number of hours Gary had the tuxedo, we will substitute y for 95 and calculate x to be 7 hours. and to solve the amount Gary will pay if Gary has the tuxedo for 24 hours, we substitute x for 24 and calculate y to be 180 dollars
