Question

Each year a school sends 50 students to a conference. Last year, the cost was $12.50 per student. This year, the cost per student has increased by 16%. How much will it cost to send 50 students to the conference this year

Answer 1

This year. Student numbers have not changed. However, the cost is raised by 16 percent. 12.5 * 1.16(1+0.16)= $14.5
This year, each student has to pay $14.5.
14.5 * 50= 145*5= $725

Answer 2

multiply 12.50 by 16% to find the new cost

12.50 * 1.16 = 14.50 per student

14.50 * 50 = $725
