Which situation can be modeled by a function? A. Raquel can spend $15 on 1 shirt, $30 on 2 shirts, or $30 on 3 shirts.

B. Bonnie can spend $10 on a shirt, $20 on 2 shirts, and $20 on 3 shirts.

C. Maria can spend $15 on 1 shirt, $15 on 2 shirts, or $30 on 3 shirts.

D. Natalie can spend $15 on 1 shirt, $30 on 2 shirts, or $45 on 3 shirts.

D.

Step-by-step explanation:

the simplest form of this equation would be that (x) is the number of shirts and 15 would be your (y). (1)15=15, (2)15=30 and so on.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
