Susan joined a video rental club. she paid an initiation fee of $12.75, and it costy $0.75 per video that she rented.
part a: -write an equasion to show the total amount susan paid to rent v videos.
part b: -while she was a member of the club , susan paid a total of $105.75. how many videos did she rent?

So initiation fee is 12.75

0.75 per video so
total cost = iniation fee+0.75 times number of videos or
total cost=12.75+0.75 times v
0.75 times v=0.75v so

total cost=12.75+0.75v

if total cost=105.75 then subsitute
105.75=12.75+0.75v
subtract 12.75 from both sides
93=0.75v
multiply both sides by 100 to clear decimal
9300=75v
divide both sides by 75
124=v

she rented 124 videos

A:total=12.75+0.75v
B:124 videos
