A gardener wants to develop a forecast for next year's quarterly sales of cactus trees. He has

collected quarterly sales for the past two years and expects total sales for next year $($Year $3)$ to be

$500$ cactus trees. The data clearly exhibit seasonality. How much can he expect to sell during

each quarter of next year accounting for seasonality?

$($Round your answers to $0$ decimal place, the tolerance is $\frac{+}{1}.)$
