What are the estimated total sales for the first 9 months of the campaign? million (Round to the nearest whole number.) When will the estimated total sales reach SI20 million? Use a graphing calculator to approximate the solution to the equation S(t) = 120. (Round to two decimal places as needed.)Explanation / Answer
S(t) = 18t + 190e^(0.1t) B) S = 18 * 9 + 190 *e^0.1*9 = 629.324
