15 of the flowers in a flower shop were marigolds,
13 of them were roses and the remaining 98 stalks were lilies.
- 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 lilies
= 1 -
15 -
13 = 1 -
315 -
515 = 1 -
815 =
715 7 u = 98
1 u = 98 ÷ 7 = 14
Number of stalks of flowers in the shop
= 15 u
= 15 x 14
= 210
(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 = 210
2 p = 210 - 8
2 p = 202
1 p = 202 ÷ 2 = 101
Number of stalks of flowers sold
= 1 p + 8
= 101 + 8
= 109
Answer(s): (a) 210; (b) 109
