So when one goes up, the other goes down. This is an inverse equation.
An inverse equation looks like this: y = 1/x
In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300
So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00
6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
Answer:
Step-by-step explanation:
4 hours × (¼ in)/hour = 1 in
6 hours × (½ in)/hour = 3 in
Total snowfall over ten hours = 1 + 3 = 4 in
Answer:
The easiest way to do this is to reflect Figure I over the Y axis. Then move it up 3 and left 2.
Answer:
- 455 adult tickets
- 884 student tickets
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then 1339-a is the number of student tickets sold. The revenue collected was ...
5a + 1(1339-a) = 3159
4a = 1820 . . . . . . subtract 1339, collect terms
a = 455 . . . . . . . . divide by 4; adult tickets sold
(1339-a) = 884 . . . . student tickets sold
455 adult tickets and 884 student tickets were sold.
