- What was the total number of flowers sold?
- 50% of the flowers in the shop were sold on that day. 80% of the flowers left were lavenders. How many lavenders were left?
70% =
70100 =
710 Total number of flowers = 10 u
Number of marigolds = 7 u
Number of lavenders
= 10 u - 7 u
= 3 u
3 u = 90
1 u = 90 ÷ 3 = 30
Total number of flowers sold
= 10 u
= 10 x 30
= 300
Percent of flowers left
= 100% - 50%
= 50%
50% of flowers = 300
1% of flowers = 300 ÷ 50 = 6
50% of flowers = 50 x 6 = 300
Number of flowers left = 300
Number of lavenders left
= 80% x 300
=
80100 x 300
= 240
Answer(s): (a) 300; (b) 240
