Question

a. What would be the cost of the Standard Daily Rate plus Mileage plan?
b. What would be the cost of the Unlimited Mileage plan?
c. Which is the better plan?_

Answer 1

Answer:

Part a) $\ 190$

Part b) $\ 315$

Part c) Standard Daily Rate plus Mileage plan

Step-by-step explanation:

Part a) What would be the cost of the Standard Daily Rate plus Mileage plan?

Let

y ----> the total cost

x ----> the number of kilometers

we have that

For a Luxury car

$y=70+0.30x$

For x=400 km

substitute

$y=70+0.30(400)$

$y=\ 190$

Part b) What would be the cost of the Unlimited Mileage plan?

we know that

The Unlimited Mileage plan for a Luxury car is $105 per day (see the table)

The trip are three days

so

To find the total cost multiply $105 by 3

$3(\ 105)=\ 315$

Part c) Which is the better plan?

Compare

$\ 190 < \ 315$

therefore

For this trip the better plan is the Standard Daily Rate plus Mileage plan
