Answer:
-13n + 101
Step-by-step explanation:
88, 75, 62, 49. = -13 -13 -13 = -13n + 101 (as 88+13 = 101)
Set x as adult tickets.
Set y as children's tickets.
x + y = 15
30x + 20y = 270
Solve for x in the first equation.
x + y = 15
x = 15 - y
Plug this into the second equation.
30x + 20y = 270
30(15 - y) + 20y = 270
450 - 30y + 20y = 270
450 - 10y = 270
-10y = -180
y = 18
If there is 18 childrens tickets, there should be -3 adult tickets.
This is impossible, and this impossible answer occured because the question is written wrong.
There are a total of 15 tickets
The smallest costing ticket is the childrens ticket, which costs 20$.
If he only bought children tickets, this would be 20x15 which is 300$.
300$ is over 270$, which makes the question impossible.
(2 5/6):2 = (2 5/6) * 1/2 = (12/6 + 5/6)*1/2 = 17/6*1/2 = 17/12 = 1 5/12
