Answer:
A
Step-by-step explanation:
<span>"The company pays $55 a day for food and lodging and $0.45 for each mile traveled" means that if she travels
m miles and is on a trip for
x days then Rita will receive:
55x + 0.45m dollars.
Rita drove 300 miles, means that m=300. Thus </span>
55x + 0.45m becomes <span>
</span>
(dollars.)
She was reimbursed $2,335 means that
.
Part A:
.
Part B:
We are given the equation 55x+135=2,335. Subtracting 135 from both sides we have:
55x=2,335-135=2,200.
Dividing both sides by 55, we get: x=2,200/55=40.
Part C: since x represents the number of days Rita spend on this trip, and x=40, then Rita spent 40 days on this trip.
The answer is: "
1 " .

x = 1 " .
______________________________________________________Explanation:______________________________________________________Write as a fraction:
______________________________________________________ ;
Reduce the "
" to "
:
Since "(4/2) = (4÷2) / (2÷2) " = "(2/1)" ;
________________________________________________________And we rewrite as:
________________________________________________________ ;
as we can see: "
x = 1 " .

The unit rate is the rate of change per day or the slope.
To get the slope of the line, we use the slope formula:
Where is point 1 on the line and tex](x_{2},y_{2})[/tex] is point 2 on the line.
Let's take 2 points from the line and calculate the slope. We will take the points (0,0) and (1,3) (any two points on the line will give the correct answer).
