Fraction of the earnings left after the sale of 6 lavenders and 17 daffodils
= 1 -
16 =
56 The rest of the earnings is repeated. LCM of 5 and 4 is 20.
Cost of 1 lavender = 1 u
Cost of 1 daffodil = 2 u
Cost of 6 lavenders = 6 x 1 u = 6 u
Cost of 17 daffodils = 17 x 2 u = 34 u
Total cost of 6 lavenders and 17 daffodils
= 6 u + 34 u
= 40 u
424 of the earnings → 40 u
124 of the earnings → 40 u ÷ 4 = 10 u
1524 of the earnings → 15 x 10 u = 150 u
Number of lavenders sold that contributed to the rest of the earnings
= 150 u ÷ 1 u
= 150
524 of the earnings → 5 x 10 u = 50 u
Number of daffodils sold that contributed to the rest of the earnings
= 50 u ÷ 2 u
= 25
Number of flowers sold
= 6 + 17 + 150 + 25
= 198
Answer(s): 198
