The marginal cost of drilling an oil well depends on the depth at which you are drilling; drilling becomes more expensive, per meter, you dig deeper into the earth. The fixed costs are 1,000,000 riyals (the riyal is the unit of currency of Saudi Arabia), and, if x is the depth in meters, the marginal costs are C'(x) = 3000 + 14x riyals/meter. Find the total cost of drilling a 500-meter well. Do not use commas in your submitted answer. The cost is i riyals.
