1. What does [tex]c(3)=60[/tex] mean in terms of the problem?



Answer :

To understand the meaning of [tex]\( c(3) = 60 \)[/tex] in terms of this problem, let's break it down step-by-step:

1. Identify Variables:
- [tex]\( c(x) \)[/tex]: This represents the cost of renting the truck for [tex]\( x \)[/tex] days.

2. Given Value:
- [tex]\( c(3) = 60 \)[/tex]

This means we are given the specific cost when the truck is rented for 3 days.

3. Interpretation:
- The notation [tex]\( c(3) = 60 \)[/tex] tells us that if the truck is rented for 3 days, the total rental cost amounts to 60 dollars.

Therefore, [tex]\( c(3) = 60 \)[/tex] means that the cost of renting the truck for 3 days is 60 dollars. This value is directly obtained from the problem and the table provided which shows the rental costs for different days.
