Group Title
A baseball team plays in a stadium that holds 51,000 spectators. With ticket prices at $10, the average attendance had been 38,000. When ticket prices were lowered to $8, the average attendance rose to 42,000. Find the demand function (price p as a function of attendance x), assuming it to be linear??

With ticket prices at $10, the average attendance had been 38,000 means x = 38000 p = 10 giving you one point (38000, 10)

When ticket prices were lowered to $8, the average attendance rose to 42,000 means x = 42000 p = 8 so another point is (42000, 8)

the slope is way to big

m = (y2y1)/(x2x1) m = ( 8 10)/(4200038000) m = 2/4000 m = 1/2000 So the slope of the line that passes through the two points is 1/2000

and how u find b?

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
y = mx + b y = (1/2000)x + b 38000 = (1/2000)(10) + b solve for b

im getting b=7600001/200 n i believe thats way too big

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
38000 = (1/2000)(10) + b 38000 = 1/200 + b 38000 + 1/200 = b 7600000/200 + 1/200 = b 7600001/200 = b b = 7600001/200 b = 38000.005

maybe you entered the fraction in wrong, try it in decimal form
