Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Answer to Problem 44E

  c(h)=35+47.5h

Explanation of Solution

Given information:

Service charges for every service call = $35

Additional charges per hour for working on each job = $47.50

The given condition is ‘cost of a service call (c) that takes h hours to complete’.

Calculation:

The formula for the given equation is as follows:

  Total cost service for h hours=Base price + Additional charge per hour

Thus, the function c(h) representing the given situation is as follows:

  c(h)=35+47.5h

b.

To determine

To find: the cost of 214 hour service call.

Answer to Problem 44E

$141.88

Explanation of Solution

Given information:

Service charges for every service call = $35

Additional charges per hour for working on each job = $47.50

Cost of a service call is represented by c and hours to complete job is represented by h .

  h=214=2.25

Calculation:

The function evaluated is as follows:

  c(h)=35+47.5h

Put h=2.25 in the above equation and solve as follows c(h) :

  c(2.25)=35+47.5(2.25)=35+106.875=141.88

Thus, the cost of service call for 214 hour is $ 141.88 .
