A school is having a fund raiser in which the students sell calendars and raffle tickets each calendar costs $18 each raffle ticket cost $7 if student sold 7 calendars and 5 raffle tickets simplify and find how much money the student should collect

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

ratio is 2 : 9

the answer is three

13.5 : 3

the answer is 21%.

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
