14 of the flowers in a flower shop were carnations,
13 of them were lavenders and the remaining 90 stalks were sunflowers.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 6 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were sunflowers
= 1 -
14 -
13 = 1 -
312 -
412 = 1 -
712 =
512 5 u = 90
1 u = 90 ÷ 5 = 18
Number of stalks of flowers in the shop
= 12 u
= 12 x 18
= 216
(b)
Number of stalks of flowers sold = 1 p + 6
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 6
= 2 p + 6
2 p + 6 = 216
2 p = 216 - 6
2 p = 210
1 p = 210 ÷ 2 = 105
Number of stalks of flowers sold
= 1 p + 6
= 105 + 6
= 111
Answer(s): (a) 216; (b) 111
