To find the cost of labor subtract 63 from 551.75
Cost of labor= 551.75 - 63
= $ 488.75
To find cost of labor per hour, divide 488.75 by the time taken to repair
488.75/4.25 = $115
Answer:
Slope (m) =
ΔY
ΔX
=
1
2
= 0.5
θ =
arctan( ΔY )
ΔX
= 26.565051177078°
ΔX = 5 – 1 = 4
ΔY = 8 – 6 = 2
Distance (d) = √ΔX2 + ΔY2 = √20 = 4.4721359549996
Equation of the line:
y = 0.5x + 5.5
or
y =
1 x
2
+ 11
2
When x=0, y = 5.5
When y=0, x = -11
20 minutes × 2 = 40 minutes
41 questions × 2 = 82 questions
40 minutes × 2 = 80 minutes
82 questions × 2 = 164 questions
