A vendor at a ball game sells hotdogs. She found that when she sells hotdogs for $1.00 that she can sell 500 of them. If she raises the price to $1.50 she only sells 400. Assuming a linear relationship bA vendor at a ball game sells hotdogs. She found that when she sells hotdogs for $1.00 that she can sell 500 of them. If she raises the price to $1.50 she only sells 400. Assuming a linear relationship between hotdogs sold and the price, come up with the equation of the line that models hotdog sales.etween hotdogs sold and the price, come up with the equation of the line that models hotdog sales.
Explanation / Answer
Points are (1,500),(1,50, 400)
Slope = (400-500)/(1.5-1) = -100/0.5 =-200
Using point slope form which is
s-s1=m(p-p1)
s-500=-200(p-1)
s= -200p +700
