Answer
I The Turner family spent at least $100 each week.
A) I only
Step by step explanation
By looking at the graph. We can interpret the following information.
1st week = $145
2nd week = $105
3rd week = $125
4th week = $200
5th week = $150
From the above information.
The Turner family spent at least $100 each week.
The other statements are false.
Therefore, the answer A) I only

Answer:
257.5 mph
332.5 mph
Step-by-step explanation:
The initial distance between the two planes is 960 miles, while the final distance (after t=1.5 h) is 75 miles, so the total distance covered by the two planes in 1.5h is
miles
Calling v1 and v2 the velocities of the two planes, we have the following equations:
(1) 
--> velocity of plane 1 exceeds velocity of plane 2 by 75 mph
(2) 
--> the total distance covered by the two planes is 885 miles (t=1.5 h is the time, and the products v1 t and v2 t represent the distance covered by each plane)
Substituting t=1.5 h, the second equation becomes:
By substituting (1) into this last equation, we find:
And substituting this back into eq.(1), we find
So, the speeds of the two planes are
257.5 mph
332.5 mph
