Mrs. drennan keeps a bag of small prizes to distribute to her students. she likes to keep at least three times as many prizes in the bag as she has students. the bag currently has 72 prizes in it. mrs. drennan has 26 students what is the least amount of prizes mrs drennan needs to buy ?

The least amount of prizes Mrs Drennan needs to buy = 6

Step-by-step explanation:

She likes to keep at least three times as many prizes in the bag as she has students.

If number of students is n, number of prizes she has = 3 n

Given that Mrs. drennan has 26 students

That is n = 26

Number of prizes needed = 3n = 3 x 26 = 78

Number of prizes she has = 72

Minimum prizes she need to buy = 78 - 72 = 6

The least amount of prizes Mrs Drennan needs to buy = 6
