Answer 1

Given that,

Jenna is surveying the number of trucks in parking lots.

One parking lot has 9 trucks and a total of 36 vehicles.

The next parking lot has 104 vehicles.

To find the number of trucks based on her survey.

The number of trucks in relation to the total vehicle is given by,

`=\frac{\text{ Number of trucks}}{\text{ Total vehicles}}=(9)/(36)=(1)/(4)`

The ratio of number of trucks to the total vehicle is 1/4, (based on the survey)

Given that, in the next parking lot has 104 vehicles.

Let n be the number of trucks.

we get,

`(n)/(104)=(1)/(4)`
`n=(104)/(4)`

we get,

`n=26`

The number of trucks is 26.

Answer is: option: D : 26.
