The total cost would be 200
Answer:
8 feet per second.
Step-by-step explanation:
We have been given that a car is driving away from a crosswalk. The formula 
expresses the car's distance from the crosswalk in feet, d, in terms of the number of seconds, t, since the car started moving.
We will use average change formula to solve our given problem.
Therefore, the the car's average speed over the given interval of time would be 8 feet per second.

Answer:
a 3
Step-by-step explanation:
You make 50 a day plus 3.60 per sale
Income = 50+ 3.6 s
You want to make at least 60
60 ≤ 50+ 3.6 s
Subtract 50 from each side
60 -50 ≤ 50-50 +3.6s
10 ≤ 3.6s
Divide by 3.6 on each side
10/3.6 ≤ 3.6s/3.6
2.7777777 ≤ s
You must make more than 2.7777 sales
But you cannot make part of a sale so
You must make at least 3 sales
