numbers of bulbs sold from Monday to sunday are as follows:
Monday = 6×2 =12
Tuesday = 8×2 = 16
Wednesday= 4×2 = 8
Thursday = 5×2 = 10
Friday = 7×2 = 14
Saturday = 4 ×2 = 8
sunday = 9×2 = 18
Total numbers of bulbs sold = 12 + 16 + 8 + 10 + 14 + 8 + 18 = 86
Number of bulbs one carton can hold = 9
Number of cartons needed to hold 86 bulbs = 86 ÷ 9 = 9, 5 bulbs will remain
We need one extra carton to keep the 5 bulbs.
So total cartons = 9 +1 = 10
Thus, we need 10 cartons in the given week
Monday = 6×2 =12
Tuesday = 8×2 = 16

Hey there !
Solution:
Let us calculate the total number of bulbs sold in the last week.
- Monday = 6 bulbs
- Tuesday = 8 bulbs
- Wednesday = 4 bulbs
- Thursday = 5 bulbs
- Friday = 7 bulbs
- Saturday = 4 bulbs
- Sunday = 9 bulbs
Total Number of Bulbs sold in that week = 6 + 8 + 4 + 5 + 7 + 4 + 9 = 43 bulbs
So 1 carton = 9 bulbs
=> x cartons = 43 bulbs
=> 9 × x = 43 × 1
=> x = 43 / 9
=. x = 4.7 cartons
But cartons cannot be a fraction. So rounding it off to the next nearest number, we get the number of cartons to be 5.
Hence the number of cartons needed in that week were 5.
Hope my answer helped !
