The SSG Organization plans to sell cupcakes to raise a fund. A bakery charges them P15.00 for the first 100 cupcakes. After the first 100 cupcakes they purchase up to 150 cupcakes the bakery
reduces the price to P13.50 per cupcake. After they purchased 150 cupcakes, the price lower to
P10.00 per cupcake. Write a function that models this situation. In this scenario you need to use
Piecewise function to model the situation,

whats the

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?
