Fraction of the earnings left after the sale of 6 daffodils and 17 daisies
= 1 -
14 =
34 The rest of the earnings is repeated. LCM of 3 and 5 is 15.
Cost of 1 daffodil = 1 u
Cost of 1 daisy = 2 u
Cost of 6 daffodils = 6 x 1 u = 6 u
Cost of 17 daisies = 17 x 2 u = 34 u
Total cost of 6 daffodils and 17 daisies
= 6 u + 34 u
= 40 u
520 of the earnings → 40 u
120 of the earnings → 40 u ÷ 5 = 8 u
620 of the earnings → 6 x 8 u = 48 u
Number of daffodils sold that contributed to the rest of the earnings
= 48 u ÷ 1 u
= 48
920 of the earnings → 9 x 8 u = 72 u
Number of daisies sold that contributed to the rest of the earnings
= 72 u ÷ 2 u
= 36
Number of flowers sold
= 6 + 17 + 48 + 36
= 107
Answer(s): 107
