At a chairity basketball game, 450 tickets were sold to students at a school. the remaining x tickets were sold to the public. the prices of the two types of tickets are shown. when all the tickets were sold $10,500 was collected. how many tickets were sold to the public?

(student cost $15)
(public cost $25)

you could make a chart using guess and check

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?

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
