Question

3. 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%.
What is the total cost to send 50 students to the
conference this year?
a.$625
b.$633
c.$725
d.$841

Answer 1

Answer: C. $725

Step-by-step explanation: To find the answer, let's first calculate the increase. A 16% increase causes the cost to go up by 16% of its own value, so let's calculate that by doing 0.16 x 12.5, giving us 2. Next, we add 2 to 12.50, giving us 14.5. Finally, we multiply 14.5 by 50 to find the cost for 50 students, giving us $725. So, $725 is our answer.

Hope this helped :D
