64%

Explanation:

M = O A P B

35 50 30 45 Store 1

25 30 40 40 Store 2

70 50 60 55 Store 3

N = ʺIn seasonʺ ʺOut of seasonʺ

$3.30 $2.00

$1.50 $5.70

$4.20 $4.55

$5.05 $4.00

The total for the three stores, of “in season” daily revenue for the four fruits

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

Percentage of the “out of season” peach sales represent the daily total “out of season” revenues for store 3

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%
