<span>suppose the speed = x mi/h
Overspeed cost = 115 + x - 65 = 50 + x ....... 1
Overspeed Cost = 50 + (x -65)*10 = 10x - 600 ..........2
from [1] and [2], we get,
10x - 600 = 50 + x
10x -x = 50 +600
9x = 650
x = 72.22 mi/h
hope it helps

Answer: B
Step-by-step explanation:
4(x+3)+2x=6(x+2)
4x+12+2x=6x+12
6x+12=6x+12
12=12
All real solutions
5+2(3+2x)=x+3(x+1)
5+6+4x=x+3x+3
11+4x=4x+3
11=3
No solution
