Answer: 100 rides are needed to break even.
Step-by-step explanation:
C(x)=15x+2000 - x is the number of rides.
R(x)=35 x , where x is the number of rides
35x=15x+2000
35-15x=2000~subtract 15x from both sides~
20x=2000 ~simplify~
x=2000/20 ~dividing both sides by 20~
x=100
Answer:
Approximately 490 films were rated R.
Step-by-step explanation:
Total films recently rated is 720. About 68% of the films were rated R. Thus, 68% of 720 is calculated below.

Step-by-step explanation:
Gary has $4. (given)
Mary has twice as many dollars as Gary, so Mary has 2×$4 = $8.
Larry has 4 fewer dollars than Mary, so Larry has $8 -4 = $4.
Gary, Mary, and Larry together have $4 +8 +4 = $16.
