Step-by-step explanation:

         35 50 30 45     Store 1

         25 30 40 40     Store 2

         70 50 60 55     Store 3

              $3.30             $2.00

              $1.50            $5.70

              $4.20            $4.55

              $5.05            $4.00

35* 3.30 + 50* 1.50 + 30* 4.20 + 45* 5.05 (store 1)

= 543.75

25* 3.30 + 30* 1.50 + 40* 4.20 + 40* 5.05 (store 2)

= 497.5

70* 3.30 + 50* 1.50 + 60* 4.20 + 55* 5.05 (store 3)

= 835.75

543.75 + 497.5 + 835.75 = 1877

Total “out of season” revenues for store 3

= 70* 2.00 + 50* 5.70 + 60* 4.55 + 55* 4.00

= 918

Total peaches sale in "out of season"

= 30(4.55) + 40(4.55) + 60(4.55)

= 591.5

Percentage = 591.5/918 * 100%

                    = 64%
