(a) The number of bulbs sold on Friday = $7\times 2=14$.

(b) On Sunday the maximum number of bulbs were sold.

(c) On both Wednesday and saturday, 8 bulbs were sold.

(d) On Wednesday and saturday, the minimum number of bulbs (8) were sold.

(e) Total number of bulbs sold in the weekend =

$\\=(6+8+4+5+7+4+9)\times 2\\ =43\times 2\\ =86$

$\frac{86}{9}=9 +\frac{5}{9}$

Number of cartons required = 9 + 1 = 10 ( we cannot have fractional number of boxes)
