Find the regression equation in the form y = ax3 + bx2 + cx + d that best approximates the data. Express the values of a, b, c, and d to the nearest hundredth. (1 mark) b. Use the equation to nd the number of boxes, to the nearest whole number, that the team will sell if they charge $4.35 per box. (1 mark) c. One year, the team only sold 366 boxes of chocolates.
