110 of the flowers in a flower shop were carnations,
14 of them were marigolds and the remaining 195 stalks were daisies.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 18 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were daisies
= 1 -
110 -
14 = 1 -
220 -
520 = 1 -
720 =
1320 13 u = 195
1 u = 195 ÷ 13 = 15
Number of stalks of flowers in the shop
= 20 u
= 20 x 15
= 300
(b)
Number of stalks of flowers sold = 1 p + 18
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 18
= 2 p + 18
2 p + 18 = 300
2 p = 300 - 18
2 p = 282
1 p = 282 ÷ 2 = 141
Number of stalks of flowers sold
= 1 p + 18
= 141 + 18
= 159
Answer(s): (a) 300; (b) 159
