Q:

A charity organization had to sell 18 tickets to their fundraiser just to cover necessary production costs. They sold each ticket for $45. Let y represent the net profit (in dollars) when they have sold x tickets.Which of the following information about the graph of the relationship is given?Choose 1 answer:ASlope and x-intercept(Choice B)BSlope and y-intercept(Choice C)CSlope and a point that is not an intercept(Choice D)Dx-intercept and y-intercept(Choice E)Ey-intercept and a point that is not an intercept(Choice F)FTwo points that are not intercepts

Accepted Solution

A:
Answer:Since each Ticket cost $45 , then the number of ticket sold should be multiplied by the cost of 1 ticket , from the question, it was said that x tickets were sold, i.e the amount will be $45 multiplied by x , which is $45x. To find the profit , then we must find the cost of 18 tickets which will give us the cost price and then subtract it from the selling price ($45x).The cost of 18 = 18 x $45 = $ 810profit = $45x - 810i.e y = 45x -810clearly, comparing with the equation y = mx +c , we have a slope and y-interceptStep-by-step explanation:
