15 of the flowers in a flower shop were carnations,
13 of them were orchids and the remaining 119 stalks were lilies.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 5 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were lilies
= 1 -
15 -
13 = 1 -
315 -
515 = 1 -
815 =
715 7 u = 119
1 u = 119 ÷ 7 = 17
Number of stalks of flowers in the shop
= 15 u
= 15 x 17
= 255
(b)
Number of stalks of flowers sold = 1 p + 5
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 5
= 2 p + 5
2 p + 5 = 255
2 p = 255 - 5
2 p = 250
1 p = 250 ÷ 2 = 125
Number of stalks of flowers sold
= 1 p + 5
= 125 + 5
= 130
Answer(s): (a) 255; (b) 130
