17 of the flowers in a flower shop were peonies,
12 of them were marigolds and the remaining 90 stalks were poppies.
- 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 poppies
= 1 -
17 -
12 = 1 -
214 -
714 =
514 5 u = 90
1 u = 90 ÷ 5 = 18
Number of stalks of flowers in the shop
= 14 u
= 14 x 18
= 252
(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 = 252
2 p = 252 - 18
2 p = 234
1 p = 234 ÷ 2 = 117
Number of stalks of flowers sold
= 1 p + 18
= 117 + 18
= 135
Answer(s): (a) 252; (b) 135
