A company that produces ribbon has found that the marginal cost of producing x yards of fancy ribbon is given by Upper C prime left parenthesis x right parenthesisC′(x)equals=negative 0.00001 x squared minus 0.02 x plus 49−0.00001x2−0.02x+49 for x less than or equals 1400x≤1400​, where Upper C prime left parenthesis x right parenthesisC′(x) is in cents. Approximate the total cost of manufacturing 14001400 yards of​ ribbon, using 5 subintervals over left bracket 0 comma 1400 right bracket[0,1400] and the left endpoint of each subinterval.
