Blaine is selling tickets to a rock concert. tickets in the front section cost $60 each. tickets in the back section cost $40 each. blaine has 55 tickets left to sell, and to meet his sales quota he needs to sell more than $600 in tickets from the remaining tickets.
blaine makes a profit of $40 on every ticket for the front section. he makes a profit of $25 on every ticket for the back section. what’s the maximum profit blaine can make from selling his remaining tickets?
it has to be two system of inequalities.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
