17 of the flowers in a flower shop were sunflowers,
12 of them were daffodils and the remaining 40 stalks were carnations.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 8 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were carnations
= 1 -
17 -
12 = 1 -
214 -
714 = 1 -
914 =
514 5 u = 40
1 u = 40 ÷ 5 = 8
Number of stalks of flowers in the shop
= 14 u
= 14 x 8
= 112
(b)
Number of stalks of flowers sold = 1 p + 8
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 8
= 2 p + 8
2 p + 8 = 112
2 p = 112 - 8
2 p = 104
1 p = 104 ÷ 2 = 52
Number of stalks of flowers sold
= 1 p + 8
= 52 + 8
= 60
Answer(s): (a) 112; (b) 60
