A moving company charges a flat rate of $75 plus an additional $0.19 per miles driven. Which inequality correctly represents how
1 answer:
Answer:
Step-by-step explanation:
Given : A moving company charges a flat rate of $75 plus an additional $0.19 per miles driven.
To Find : Which inequality correctly represents how far the company must drive to earn at least $100?
Solution:
Fixed charge = $75
Cost of 1 mile = $0.19
Let m be the no. of miles
So, Cost of m miles = 0.19m
So, Total cost = 75+0.19m
Now we are given that the company must drive to earn at least $100.
So, Inequality becomes :
So, the company must drive 132 or more miles to earn at least $100.
Hence inequality correctly represents how far the company must drive to earn at least $100 is :

We are given the two functions 
and 
. Since the question is asking us for the value of x when f(x) is equal to g(x), all we need to do is equate the respective expressions together. This is what the result should be:
Now, just solve for x. If you want to save some time, you can use logic and then algebra. To do this, look at the square root. We cannot have an imaginary number, so we can rule out the first two options. Now, we are left with x = 2 and x = 4. When we plug in each x-value to the equation, only 4 works out with a result of 0.5 = 0.5. Therefore, the solution to f(x) = g(x) is D) x = 4. Hope this helps and have a great day!
