The cable company charges a monthly fee of 45$ Each movie rental is $ 1.99 you owe 68.88 how many movies did u rent

Answer 1

If you do not rent any vidoes you will be charged $45 no matter what, so...

Movies + 45 = total charge

each movie is 1.99 and you owe (total charge) $68.88

equation:

1.99x + 45 = 68.88

-45 -45 (subtract 45 from each side to keep equation balanced)

1.99x = 23.88 (now divide both sides by 1.99 to ge x alone)

x = 12

you rented 12 movies
