Answer:
and 
Step-by-step explanation:
A simple way to solve this problem is to plug the corresponding x and y into the function. We need only one pair since all the functions are quasi-linear (y=kx) and the increase is proportional.
In when x=3, y=15/4≈2.14
In 
when x=3, y=1.8
In when x=3, y≈2.33
In 
when x=3, y≈1.90
We can observe that in two cases, and , y is greater than 2.
(1.75 + 2 x 0.25 + 5 x 0.05) x 24= 17
first you have to add the -4 to the -2 and you get 2. so 2x=2 then you divide 2 by 2x and get x=1
She can get $12. X= ($42)(2/7)
5(2x-3)-(x+8)=13
10x-15-x-8=13
9x-23=13
9x=36
x=4
