The souvenir shop at the ballpark sells signed baseballs for $2 dollars each and signed miniature bats for $6 each. Jay can spend at most $12 to buy no more than 4 items. Create a system of inequalities to model this situation, and then graph the solution set. Which solution results in jay spending al his money to buy 4 items?

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

entering that problem on the tube might get you an answer

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
