15 of the flowers in a flower shop were sunflowers,
14 of them were tulips and the remaining 132 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 16 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 -
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 + 16
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 16
= 2 p + 16
2 p + 16 = 240
2 p = 240 - 16
2 p = 224
1 p = 224 ÷ 2 = 112
Number of stalks of flowers sold
= 1 p + 16
= 112 + 16
= 128
Answer(s): (a) 240; (b) 128
