A stall was selling flowers. ¹₆ of the earnings are from the sale of 8 roses and 11 sunflowers. Of the rest of the earnings, ²₃ are from the sale of roses and ¹₃ are from the sale of sunflowers. Each sunflower costs twice as much as each rose. How many flowers were sold?

8 roses and 11 sunflowers	Rest of the earnings		Total earnings
1x3	5x3
	Roses	Carnations
	2x5	1x5
3	10	5	18

Fraction of the earnings left after the sale of 8 roses and 11 sunflowers
= 1 - ¹₆
= ⁵₆ 

The rest of the earnings is repeated. LCM of 5 and 3 is 15.

Cost of 1 rose = 1 u
Cost of 1 sunflower = 2 u

Cost of 8 roses = 8 x 1 u = 8 u
Cost of 11 sunflowers = 11 x 2 u = 22 u

Total cost of 8 roses and 11 sunflowers
= 8 u + 22 u
= 30 u

³₁₈ of the earnings → 30 u 
¹₁₈ of the earnings → 30 u ÷ 3 = 10 u 

¹⁰₁₈ of the earnings → 10 x 10 u = 100 u 

Number of roses sold that contributed to the rest of the earnings
= 100 u ÷ 1 u
= 100

⁵₁₈ of the earnings → 5 x 10 u = 50 u

Number of sunflowers sold that contributed to the rest of the earnings
= 50 u ÷ 2 u
= 25

Number of flowers sold
= 8 + 11 + 100 + 25
= 144

Answer(s): 144
