Question

Three fourth of the students and an additional 18

students at the school purchased a spirit shirt during the
last fundraiser. If 336 shirts were ordered, how many
students are there in the school?

Answer 1

424

Explanation:

let 's' = number of students

3/4s + 18 = 336

3/4s = 318

3s = 1272

s = 1272/3 = 424
