19 of the flowers in a flower shop were tulips,
13 of them were roses and the remaining 50 stalks were orchids.
- 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 orchids
= 1 -
19 -
13 = 1 -
19 -
39 =
59 5 u = 50
1 u = 50 ÷ 5 = 10
Number of stalks of flowers in the shop
= 9 u
= 9 x 10
= 90
(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 = 90
2 p = 90 - 8
2 p = 82
1 p = 82 ÷ 2 = 41
Number of stalks of flowers sold
= 1 p + 8
= 41 + 8
= 49
Answer(s): (a) 90; (b) 49
