15 of the flowers in a flower shop were lavenders,
12 of them were poppies and the remaining 36 stalks were carnations.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 10 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were carnations
= 1 -
15 -
12 = 1 -
210 -
510 = 1 -
710 =
310 3 u = 36
1 u = 36 ÷ 3 = 12
Number of stalks of flowers in the shop
= 10 u
= 10 x 12
= 120
(b)
Number of stalks of flowers sold = 1 p + 10
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 10
= 2 p + 10
2 p + 10 = 120
2 p = 120 - 10
2 p = 110
1 p = 110 ÷ 2 = 55
Number of stalks of flowers sold
= 1 p + 10
= 55 + 10
= 65
Answer(s): (a) 120; (b) 65
