The total cost function is the sum of the two given functions, and this is equal to:
c(t) = 190 + 70*t
<h3>
How to find the linear function for the total cost?</h3>
We know that:
- The plumber charges p(t) = 115 + 25*t
- The electrician charges e(t) = 55*t + 75.
If she hires both of them for the same time t, then the total cost function will be given by the sum of the two above functions, we will get:
c(t) = p(t) + e(t)
c(t) = (115 + 25*t) + (55*t + 75)
c(t) = (115 + 75) + (55*t + 25*t)
c(t) = 190 + 70*t

Answer:
the answer is <u><em>2)</em></u> 10<10
Step-by-step explanation:
10<10 has to be the answer? why?
10<10) 10 cannot be greater than 10
the correct the inequality for 10<10 would to change it to 10 = 10

Place in ascending order: 4 6 8 15 15 17 17 18 20 20
middle numbers = 15 and 17
(15+17)/2 = 16
8(hours)-5=67
8(h)-5=67
8h-5=67
8h=67+5
8h=72
H=72/8
h=9
