Question 4 of 25 After the booster club sold 40 hotdogs at a football game, it had $90 in profit. After the next game, it had sold a total of 80 hotdogs and had a total of $210 in profit. Which equation models the total profit, y, based on the number of hotdogs sold, x? O A. y-99 = 2.6(x - 40) B. y+90 = 3(x + 40) c. y - 90 = 3(x - 40) D. Y+90 = 2.6(x + 40) SUBNAIL

the answer is 11.2 (i know i’m late)

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
