17 of the flowers in a flower shop were roses,
12 of them were marigolds and the remaining 30 stalks were peonies.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers sold was 8 more than the number of flowers left. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were peonies
= 1 -
17 -
12 = 1 -
214 -
714 =
514 5 u = 30
1 u = 30 ÷ 5 = 6
Number of stalks of flowers in the shop
= 14 u
= 14 x 6
= 84
(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 = 84
2 p = 84 - 8
2 p = 76
1 p = 76 ÷ 2 = 38
Number of stalks of flowers sold
= 1 p + 8
= 38 + 8
= 46
Answer(s): (a) 84; (b) 46
