Question

Thrift rents a compact car for $33 per day, and General rents a similar car for $20 per day plus an initial fee of $65. For how many days d would it be cheaper to rent from General?

Answer 1

Answer:

The Correct answer would be, When Days will be greater than 5

Explanation:

There are two companies who give cars on rent.

Thrift rents a car for $33 per day

i-e

T=$33D

General rents the car for $20

i-e

G=$20D

and general charges an initial fee of $65

So  

G=$20 + $65

So according to question, for how many days it would be cheaper to rent from General.

So when charges by general are less than charges by thrift, as shown below:

65+20D < 33D

65 < 33D-20D

65 < 13D

D > 5

So the answer would be 5 Days.
