15 of the flowers in a flower shop were daffodils,
14 of them were daisies and the remaining 143 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 14 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were carnations
= 1 -
15 -
14 = 1 -
420 -
520 = 1 -
920 =
1120 11 u = 143
1 u = 143 ÷ 11 = 13
Number of stalks of flowers in the shop
= 20 u
= 20 x 13
= 260
(b)
Number of stalks of flowers sold = 1 p + 14
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 14
= 2 p + 14
2 p + 14 = 260
2 p = 260 - 14
2 p = 246
1 p = 246 ÷ 2 = 123
Number of stalks of flowers sold
= 1 p + 14
= 123 + 14
= 137
Answer(s): (a) 260; (b) 137
