Mr Rogers want to buy candies for some of the students who are attending
the trip to the zoo
There are 7 classes, and each dass has 28 students
There will be 12 adults going with the students.
• Mr. Rogers knows he can get a good price by buying tickets in packs
of 20
How many packs of tickets should Mr Rogers buy?
(A) 100 packs
(C) 200 packs
(B) 10 packs
(D) 20 packs

The correct answer is B. 10 packs.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of students = 28 in each class

Number of classes = 7

Number of adults = 12

Number of buying tickets per pack = 20

2. How many packs of tickets should Mr Rogers buy?

Let's find the number of tickets to the zoo necessary, this way:

Number of tickets = Number of classes * Number of students + Number of adults

Number of tickets = 7 * 28 + 12

Number of tickets = 196 + 12

Number of tickets = 208

If Mr. Rogers buys 10 packs, it will be enough for all the students and 4 teachers. Buying additional 8 individual tickets would be for sure less expensive than buying 20 packs, unless the group is planning a second visit later.

The correct answer is B. 10 packs.

1. minimum

2. 6400

3. eight

hope this !
