Answer:

13/24

hope it helped!!

tell me if you need an explanation

Edit:

Step 1 We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator. So we multiply 7 by 3, and get 21. Then we multiply 1 by 8, and get 8. Next we give both terms new denominators 8 × 3 = 24. So now our fractions look like this: 21/24−8/24

Step 2 Since our denominators match, we can subtract the numerators. 21 − 8 = 13 So the answer is: 13/24

The fee for a service call from a plumber can be modeled with the function C(h)= 75 + 20h, where C is the total cost of the serv
Lynna [10]

Answer:

20 ; $135 ; service charge for 3 hours spent is $135

Step-by-step explanation:

Given that :

Service fee equation model :

C(h)= 75 + 20h

C = total cost of the service call

h = number of hours the plumber spends working on the problem

The charge per hour is the gradient or slope of the linear equation. From the equation, the slope is of the equation is related to bx from. The general form of a linear equation where b = gradient or slope(charge per hour) and x = number of hours

bx = 20h

b = 20

Charge per hour = 20

C(3) = 75 + 20(3)

75 + 60 = 135

This means that total service call charge for a plumber who spends three hours fixing a problem is $135
