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

Answer 1

I think it would be 300, because 15% of x=45, so .15x=45, x= 45/.15=300
