110 of the flowers in a flower shop were daffodils,
14 of them were carnations and the remaining 221 stalks were peonies.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers sold was 12 more than the number of flowers left. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were peonies
= 1 -
110 -
14 = 1 -
220 -
520 =
1320 13 u = 221
1 u = 221 ÷ 13 = 17
Number of stalks of flowers in the shop
= 20 u
= 20 x 17
= 340
(b)
Number of stalks of flowers sold = 1 p + 12
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 12
= 2 p + 12
2 p + 12 = 340
2 p = 340 - 12
2 p = 328
1 p = 328 ÷ 2 = 164
Number of stalks of flowers sold
= 1 p + 12
= 164 + 12
= 176
Answer(s): (a) 340; (b) 176
