Answer 1

Answer:

budget sales per season

Seaon  Year 5

winter   1,473

spring   1,934

summer  2,267

fall              826

Explanation:

First, we calcualte the average per season:

Seaon Year 1 Year 2 Year 3 Year 4  Average per season

winter 1440 1240 1000  920.00   1,150.00

spring 1500 1440 1600  1,500.00  1,510.00

summer 1040 2140 2000   1900  1,770.00

fall          600 770            690   520  645.00

 

Now, we cross multiply to get the next year values

Seaon  Average per season  Year 5

winter  1,150.00   1,472.91  (1150/5075 x 6500)  

spring  1,510.00   1,933.99  

summer  1,770.00   2,267.00  

fall           645.00   826.11  

        5,075.00   6,500.00
