Answer:
5x + 8y ≥ 1200
x + 2y ≤ 500
Step-by-step explanation:
Let x = number of $5 tickets
Let y = number of $8 tickets
Worth of ticket that must be sold = at least $1200
No more than 500 students can fit in the gym
Ticket worth equation :
Cost * number of tickets ≥ 1200
5x + 8y ≥ 1200
Number of students :
Person = 1
Couple = 2
x + 2(y) ≤ 500
x + 2y ≤ 500

Answer:
Mode = 19.
Median = 23.
Step-by-step explanation:
Arrange in ascending order:
8 9 12 15 17 18 19 19 20 22 24 25 26 27 28 31 34 36 40 43
The modal amount is the one which occurs most , which is 19.
The median is the middle value of the 20 amounts.
As there is an even number of amounts the median is the mean of the 2 middle numbers:
Median = (22 + 24) / 2
= 23.
