15 of the flowers in a flower shop were poppies,
13 of them were marigolds and the remaining 91 stalks were daffodils.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 5 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were daffodils
= 1 -
15 -
13 = 1 -
315 -
515 = 1 -
815 =
715 7 u = 91
1 u = 91 ÷ 7 = 13
Number of stalks of flowers in the shop
= 15 u
= 15 x 13
= 195
(b)
Number of stalks of flowers sold = 1 p + 5
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 5
= 2 p + 5
2 p + 5 = 195
2 p = 195 - 5
2 p = 190
1 p = 190 ÷ 2 = 95
Number of stalks of flowers sold
= 1 p + 5
= 95 + 5
= 100
Answer(s): (a) 195; (b) 100
