Solve the problem.The cost and revenue equations for a company which produces laptops are: Cost: y = 5000x + 65,000 Revenue: y = 10,000x[where x is the number of laptops and y is the amount (of cost or revenue) in dollars]The equations are displayed in the graph below. The revenue equation is represented by the dashed line and the cost equation by the black line. Use the graph to determine the number of laptops that must be sold for the cost to equal the revenue and then use the equations to find this exact dollar amount.
A. $130,000 B. $13 C. $43,333 D. $65,000
