Answer:
Marisa can rent 10 movies this month including the $5.00 membership fee. Not including the membership fee she could rent 14 movies this month. Her mistake is was rounding the 10.8 up when she should have rounded it down, unless she can get 10 8/10 of a movie.
Step-by-step explanation:
We set up the equation (70+64+83+x)/4=75
Multiply by 4 on both sides: 70+64+83+x=300
Combine like terms on left side: 217+x=300
Subtract 217 from both sides: x=83
