Each friend spent $50 (50+50+50= 150)
Sarah spent twice as much as them150*2=300
altogether they spent $150+$300= $450
(just edited sorry for previous mistake)
Answer: D. (4,3)
The x coordinates of A and B are 9 and -1 in that order. Add them up to get 9+(-1) = 9-1 = 8. Then divide by two to end up with 8/2 = 4. The midpoint has an x coordinate of 4.
Repeat for the y coordinates. Add them up: 8+(-2) = 8-2 = 6. Then divide by two: 6/2 = 3. The midpoint has an y coordinate of 3.
Those two coordinates pair up to get (x,y) = (4,3) which is the midpoint of segment AB.

Slope =0
total cost = 50 +12x
where x = number of months
x= 6 months
total cost = 50 +12(6) = 50 +72 =122
the cost for 6 months is $122
