The width would be 16
4x22=88
1408-88= 1320
22x16x4= 1408
The number of people is extra information, all you need is 153.82*2 (for the trip and back) * .645, which I believe will be $198.43, but it might be best to check that math to be safe
Answer:
y = +3/2x + 12
Step-by-step explanation:
get slope
get midpoint
get b
1.
(-7,8) and (-1,4)
get slope
(y₂ - y₁) / (x₂ - x₁)
slope is -2/3
perpendicular slope is the negative reciprocal :
+3/2
y=mx + b
y=+3/2x + b
get midpoint :
(x₁ + x₂)/2, (y₁ + y₂)/2
(-4,6)
get b
y=mx + b
6=+3/2(-4) + b
6= -6+ b
b = 12
y = +3/2x + 12
