Answer: B) Profit per shirt goes from $10 to $15
================================================
Explanation:
Focus on the two points (2,0) and (3,10). The slope of the line through these points is
m = (y2-y1)/(x2-x1)
m = (10-0)/(3-2)
m = 10
Meaning the profit per shirt for this line is $10 per shirt.
----------
Now move onto the other line. Focus on the points (9,40) and (11,70)
m = (y2-y1)/(x2-x1)
m = (70-40)/(11-9)
m = 15
The profit per shirt has gone up to $15 per shirt
Answer:
His average speed for the rest of the journey was of 48mph.
Step-by-step explanation:
We use the following relation to solve this question:
In which v is the velocity, d is the distance and t is the time.
First 32 miles at an average speed of 64mph.
So the time for these 32 miles is:
Rest of the trip:
200 - 32 = 168 miles in 4 - 0.5 = 3.5 hours. So the average speed is of:
His average speed for the rest of the journey was of 48mph.
