The maximum price is $151 250.

 

Quadratics Math 2200.

Answer 1

$151 sells 250

$70 sells 2,000

$50 sells how many? more than 2,000

linear relation assumed

points (250, 151), (2000, 70)

slope = -81/1750 = (P-70)/(q-2000)

for P =50

-81/1750 = (50-70)/(q-2000)

-81/1750 =-20/(q-2000)

-81q + 162000=-20(1750)=- 35000

-81q = -35000-162000= - 197000

q = 197000/81 = about 2,432.09877

tickets sold at $50 = about 2,432
