Answer:
The meal must cost less than or equal to 19.92
Step-by-step explanation:
Let x be the cost of the mean
First find the tax
tax = x* 5.5%
=.055x
Then find the tip
tip = x * 20%
tip = .20x
Add the total cost together
total cost = meal + tax + tip
=x + .055x + .20x
=1.255x
This must be less than or equal to 25
1.255x ≤ 25
Divide each side by 1.255
1.255x/1.255 ≤ 25/1.255
x ≤ 19.92
The answer is 88. Median is middle number and you don’t count the same number twice

Explanation:
Let’s take kids as x and adults as y
According to the question,
5x + 2y = 25 (1)
3x + 1y = 14 (2)
Let’s multiply (2) with 2 so take we can solve the equations
5x + 2y = 25
6x + 2y = 28
(-) (-) (-)
___________
-1x = = -3
x = 3
Substituting to get y
3x + 1y = 14
3(3) + y = 14
y = 14-9
y = 5
Answer:
Therefore, each child’s skate rental (x) costs $3 and each adults’s skate rental (y) costs $5
