Answer:
10 Kids In Each Van.
Why?
You already know that 5 students will be in 1 car. That leaves 20 students that need to be assigned to vans. Divide 20 by 2 and you get 10!
Solve for y:
5 t = 9 y + 22
5 t = 9 y + 22 is equivalent to 9 y + 22 = 5 t:
9 y + 22 = 5 t
Subtract 22 from both sides:
9 y = 5 t - 22
Divide both sides by 9:
Answer: y = (5 t)/9 - 22/9
We can see that there is a square root in the function.
As the value inside the square root should always be positive, We can conclude that (x - 6) should always be positive and can also be equal to zero.
We can set up a proportion to find this
60 x
--- = ----
100 1200
then we cross multiply and divide to solve
60 times 1200 is 72000 divided by 100 is 720
now we know his employer pays 720 out of 1200
we subtract to find out how much he pays
1200-720 is 480
fred pays 480
