Solve. Assume the exercise describes a linear relationship. When writing a linear equation, write the equation in slope-intercept form. -A vendor has learned that, by pricing carmel apples at $1.00, sales will reach 149 carmel apples per day. Raising the price to $2.00 will cause the sales to fall to 105 carmel apples per day. Let y be the number of Carmel apples the vendor sells at x dollars each. Write a linear equation that models the number of Carmel apples sold per day when the price is x dollars each.
