15 of the flowers in a flower shop were marigolds,
14 of them were poppies and the remaining 132 stalks were daffodils.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers sold was 18 more than the number of flowers left. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were daffodils
= 1 -
15 -
14 = 1 -
420 -
520 =
1120 11 u = 132
1 u = 132 ÷ 11 = 12
Number of stalks of flowers in the shop
= 20 u
= 20 x 12
= 240
(b)
Number of stalks of flowers sold = 1 p + 18
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 18
= 2 p + 18
2 p + 18 = 240
2 p = 240 - 18
2 p = 222
1 p = 222 ÷ 2 = 111
Number of stalks of flowers sold
= 1 p + 18
= 111 + 18
= 129
Answer(s): (a) 240; (b) 129
