Particular values of the marginal cost function of Kuddly Kites, a company that sells kites shaped like different animals are shown in the table below, where x is the number of kites produced and c'(x) is in dollars per kite. 152 166 180 194 208 222 236 250 264 278 292 C'(x) 2 3.25 3.75 4.25 5.25 6 6.5 7.75 8.25 9 9.75 Estimate the change in cost when the number of kites produced increases from 166 to 278 using a right-hand Riemann sum with 4 subintervals of equal width Estimate the change in cost when the number of kites produced increases from 166 to 278 using a left-hand Riemann sum with 4 subintervals of equal width
