15 of the flowers in a flower shop were lavenders,
12 of them were carnations and the remaining 30 stalks were tulips.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 14 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were tulips
= 1 -
15 -
12 = 1 -
210 -
510 = 1 -
710 =
310 3 u = 30
1 u = 30 ÷ 3 = 10
Number of stalks of flowers in the shop
= 10 u
= 10 x 10
= 100
(b)
Number of stalks of flowers sold = 1 p + 14
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 14
= 2 p + 14
2 p + 14 = 100
2 p = 100 - 14
2 p = 86
1 p = 86 ÷ 2 = 43
Number of stalks of flowers sold
= 1 p + 14
= 43 + 14
= 57
Answer(s): (a) 100; (b) 57
