Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.
<h3>Variation</h3>
y = k × x
where,
k = constant of proportionality
y = -40
x = -5
y = k × x
-40 = k × -5
-40 = -5k
k = -40/-5
k = 8
when,
y = 8 and x = 2.5
y = k × x
8 = k × 2.5
8 = 2.5k
k = 8/2.5
k = 3.2
when,
y = 5 and x = 4
y = k × x
5 = k × 4
5 = 4k
k = 5/4
k = 1.25

31.5 hours for $135

Annalise charges about 4.29 per hour.
FV = PV / (1 +r)^n
Where FV = Future Value, PV = Present Value, r = inflation rate in %,
n = number of years.
PV = $38, r = 4%, n = 3 years.
FV = 38 / (1 + 4%)^3
= 38 / (1 + 0.04)^3
= 38 / (1.04)^3 = 33.782
Hence the value 3 years from now = $33.78
