15 of the flowers in a flower shop were orchids,
12 of them were daffodils and the remaining 51 stalks were lavenders.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 18 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were lavenders
= 1 -
15 -
12 = 1 -
210 -
510 = 1 -
710 =
310 3 u = 51
1 u = 51 ÷ 3 = 17
Number of stalks of flowers in the shop
= 10 u
= 10 x 17
= 170
(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 = 170
2 p = 170 - 18
2 p = 152
1 p = 152 ÷ 2 = 76
Number of stalks of flowers sold
= 1 p + 18
= 76 + 18
= 94
Answer(s): (a) 170; (b) 94
