Answer:
Season:
Fall 262 units
Winter 391 units
Spring 178 units
Summer 569 units
Explanation:
First, we calculate the average for each season.
Then, we cross multiply for 1,400 radials to get the values:
[tex]\left[\begin{array}{cccc}Season&Y_1&Y_2&Average\\$fall&250&200&225\\$winter&320&350&335\\$spring&160&145&152.5\\$summer&635&340&487.5\\\\$total&1035&1365&1200\end{array}\right][/tex]
Now we cross multiply to get the expected sales for Year 3:
225 / 1200 * 1400 = 262
335/ 1200 * 1400 = 391
152.5/ 1200 * 1400 = 178
487.5/ 1200 * 1400 = 569
