Pare a.) $70 is what he would have left. Since each trip is $14 you would multiply that by the amount of times he went which was 11. 14x11 is $154. But you need what he has left so you take his total amount $224-$154 and get $70.
Part b.) 16 times. He has $224 total. You want to find out how many times he can go on the tool roads. We know the toll roads cost $14 each time. So you do $224/14 and get an even amount of 16. He would be able to use it 16 times before he have no money left.

Answer:
Looks complicated!
Step-by-step explanation:
PART 1):
f(x) = 3x – 5 if x < -1
Start with a filled in circle on (-1, -8). Use the slope to go up 3 and right 1 to make another point and drawn the line only going down.
Answer: WRONG.
Because correct inequality is x≤-1 not x<-1. Hence we will put a close circle not an open circle. at (-1,-8).
Also since slope is positive so graph will go upward not downward.
-----------------
PART 2):
f(x) = -2x + 3 if -1 < x < 4
Put an open circle on (-1,5) and open circle on (4, -5). Connect those points.
Answer: Correct
Because correct inequality is < or > so both end points will be open circles.
----------------
PART 3):
f(x) = 2 if x > 4
Put an open in circle on (4,2) then draw a horizontal line to the right.
Answer: WRONG.
Because correct inequality is x≥4 not x>4. Hence we will put a close circle not an open circle. at (4,2).
