Step-by-step explanation:
Sorry, but I only know for no.4 which is $130.50.
Explanation: 18 hours is 20 percent more than 15 hours.
So all we have to do is multiply 1.2 to 108.75, since multiplying 1.2 is the equivalent to 20 percent.

Answer:
y= 1/2x-3
Step-by-step explanation:
2y - x = 8
First find the slope
2y = x+8
Divide by 2
2y/2 = x/2 +8/2
y = 1/2 x +4
The slope is 1/2 ( y=mx+b where m is the slope and b is the y intercept)
When lines are parallel they have the same slope)
Using y = mx+b
y =1/2x+b
Substituting the point (4,-1) into the equation
-1 =1/2(4)+b
-1 = 2+b
-3 =b
The equation of the line is
y= 1/2x-3
The answer was A but i am found
1.557, -11.557
and hope that helps you
