Answer:
12 movies
Step-by-step explanation:
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 get x alone)
x = 12
you rented 12 movies
Equation::
value + value = value
80x + 60(50-x) = 74*50
----
80x + 60*50 - 60x = 74*50
----
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
