Question

11. For the school fete, a ticket costs 20. There are
25 students in each class and each student boue dd
ticket. If there are 50 classes in the school, then
Idir
much money was collected by the sale of ticket hen​

Answer 1

The correct answer is either 4 or 5. Because each student ticket costs $2 and each adult ticket costs $3, the total amount, in dollars, that Chris spends on x student tickets and 1 adult ticket is 2x+3.

Because Chris spends at least $11 but no more than $14 on the tickets, one can write the complete inequality 2x+3≥1.

Subtracting 3 from each side of both inequalities and then dividing each side of both inequalities by 2 yields x≥4 and x≤5.5.

Thus, the value of x must be an integer that is both greater than or equal to 4 and less than or equal to 5.5.

Therefore, x=4 or x=5.

Answer 2

Answer:

25000 (whatever currency it is) was collected.

Explanation:

Cost of ticket                                 = 20

No. of students ina class              = 25

No. of classes in the school         = 50

Therefore total money collected = 20 x 25 x 50

                                                      = 25000

Therefore 25000 (whatever cuurency it is) was collected.
