Answer 1

The total number of students that ate lunch are 300 .

Explanation:

Formula

`Percentage = (Part\ value* 100)/(Total\ value)`

As given

There are 4 lunch choices in a school cafeteria: Salad, Pizza, Spaghetti, and Sub Sandwiches.

The percentage of students that chose salad is 15%.

If 45 students chose salad.

Here

Percentage = 15%

Part value = 45

Put in the formula

`15 = (45* 100)/(Total\ value)`

`Total\ value= (4500)/(15)`

`Total\ value= 300`

Therefore the total number of students that ate lunch are 300 .
