Ferdinand is buying shirts. The store sells t-shirts for $20 each and collared shirts for $30 each. He needs a certain number of shirts but is on a budget. The graph below represents the number of t-shirts, c, and collared shirts, y, that he can buy. What is the system of inequalities represented by the graph?

answer: hey there,

the answer you are looking for is a..

hope this you!

where are the images of the functions i can only see the question you typed.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

it would open into a square depending on the type of envelope i’m not sure about the second part
