Use your knowledge of the process of “Writing an equation given two points” to solve the following problem:

A vendor has learned that, by pricing his deep fried bananas on a stick at $1.50, sales will reach 110 per day.  Raising the price to $2.50 will cause the sales to fall to 70 per day.  Let y be the number of the vendor sells at x dollars each.  Write a linear equation that models the number of sold per day when the price is x dollars each.
