A manufacturer makes a profit of $1,500 when 45 items are sold, and a profit of $2,500 when 65 items are sold.
a) Write a linear equation, in slope-intercept form, which describes the relationship between the profit, y, and the number of items sold, x.
b) Use the equation to find the expected profit if 100 items are sold?
C) Use the equation to find how many items need to be sold if the profit is to be $5,000?
