Question

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, what is the total number of students that ate lunch?
A) 150
B) 200
C) 250
Eliminate
D) 300

Answer 1

Say x = total
15% of total would look like:
0.15x
And then 45 took salad
0.15x = 45
You just need to divide 45/0.15
What does 45/0.15 = ?

Answer 2

300 thx

Answer 3
