A certain math teachers likes to keep a box of prizes to distribute to students. The math teacher likes to keep at least twice as many prizes in the box as she has students. If the math teacher currently has 109 students and the box has 88 prizes in it, Determine hw many prizes she would need to buy.

A. 109

B. 108

C. 130

D. 218

Option C

Math teacher would need to buy 130 prizes

Solution:

Given that,

Math teacher currently has 109 students and the box has 88 prizes in it

The math teacher likes to keep at least twice as many prizes in the box as she has students

So, she wants the number of prizes to be twice the number of students

Therefore,

number of prizes = 2 x 109 students

number of prizes = 2 x 109 = 218 prizes

The box has 88 prizes in it

Therefore, number of prizes she would need to buy is:

⇒ 218 - 88 = 130

Thus she would need to buy 130 prizes
