A stall was selling flowers. ¹₃ of the earnings are from the sale of 8 peonies and 10 daffodils. Of the rest of the earnings, ²₃ are from the sale of peonies and ¹₃ are from the sale of daffodils. Each daffodil costs four times as much as each peony. How many flowers were sold?

8 peonies and 10 daffodils	Rest of the earnings		Total earnings
1x3	2x3
	Roses	Carnations
	2x2	1x2
3	4	2	9

Fraction of the earnings left after the sale of 8 peonies and 10 daffodils
= 1 - ¹₃
= ²₃ 

The rest of the earnings is repeated. LCM of 2 and 3 is 6.

Cost of 1 peony = 1 u
Cost of 1 daffodil = 4 u

Cost of 8 peonies = 8 x 1 u = 8 u
Cost of 10 daffodils = 10 x 4 u = 40 u

Total cost of 8 peonies and 10 daffodils
= 8 u + 40 u
= 48 u

³₉ of the earnings → 48 u 
¹₉ of the earnings → 48 u ÷ 3 = 16 u 

⁴₉ of the earnings → 4 x 16 u = 64 u 

Number of peonies sold that contributed to the rest of the earnings
= 64 u ÷ 1 u
= 64

²₉ of the earnings → 2 x 16 u = 32 u

Number of daffodils sold that contributed to the rest of the earnings
= 32 u ÷ 4 u
= 8

Number of flowers sold
= 8 + 10 + 64 + 8
= 90

Answer(s): 90
