Let’s rethink the question with functions. If f(x) = y then y should be changing by the value of x.
Answer:
She bought 7 shirts
88 kids were going on a field trip. Each car could hold 9 kids, and 25 kids decided to ride the bus. How many cars were needed?
Step-by-step explanation:
9x=63
x=7
So from that i think the formula would be

so then you find "x" by multiplying 470 x 28 which equals 13,160. Then you divide 13,160 by 40 which equals 329.
X=329
329 students are likely to have phones
The original price is $200 because if you did 200 * 0.2, it would equal $160 which is the discounted price.
X+y= -12
xy=8
y=8/x
x+8/x=-12
x^2+12x+8=0
This has no integral
