15 of the flowers in a flower shop were lavenders,
14 of them were daisies and the remaining 132 stalks were orchids.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 8 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were orchids
= 1 -
15 -
14 = 1 -
420 -
520 = 1 -
920 =
1120 11 u = 132
1 u = 132 ÷ 11 = 12
Number of stalks of flowers in the shop
= 20 u
= 20 x 12
= 240
(b)
Number of stalks of flowers sold = 1 p + 8
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 8
= 2 p + 8
2 p + 8 = 240
2 p = 240 - 8
2 p = 232
1 p = 232 ÷ 2 = 116
Number of stalks of flowers sold
= 1 p + 8
= 116 + 8
= 124
Answer(s): (a) 240; (b) 124
