110 of the flowers in a flower shop were sunflowers,
15 of them were carnations and the remaining 126 stalks were lilies.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers sold was 20 more than the number of flowers left. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were lilies
= 1 -
110 -
15 = 1 -
110 -
210 =
710 7 u = 126
1 u = 126 ÷ 7 = 18
Number of stalks of flowers in the shop
= 10 u
= 10 x 18
= 180
(b)
Number of stalks of flowers sold = 1 p + 20
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 20
= 2 p + 20
2 p + 20 = 180
2 p = 180 - 20
2 p = 160
1 p = 160 ÷ 2 = 80
Number of stalks of flowers sold
= 1 p + 20
= 80 + 20
= 100
Answer(s): (a) 180; (b) 100
