Answer:
=−75x2+81.5x−1147.75
Step-by-step explanation:
simplify step-by-step.
x(80−75x)−(500+2(80−0.75x))−250−3(80−0.75)
Distribute:
=(x)(80)+(x)(−75x)+−500+(−2)(80)+(−2)(−0.75x)+−250+−3(80−0.75)
=80x+−75x2+−500+−160+1.5x+−250+−237.75
Combine Like Terms:
=80x+−75x2+−500+−160+1.5x+−250+−237.75
=(−75x2)+(80x+1.5x)+(−500+−160+−250+−237.75)
=−75x2+81.5x+−1147.75
