Fraction of the earnings left after the sale of 9 orchids and 17 peonies
= 1 -
14 =
34 The rest of the earnings is repeated. LCM of 3 and 5 is 15.
Cost of 1 orchid = 1 u
Cost of 1 peony = 3 u
Cost of 9 orchids = 9 x 1 u = 9 u
Cost of 17 peonies = 17 x 3 u = 51 u
Total cost of 9 orchids and 17 peonies
= 9 u + 51 u
= 60 u
520 of the earnings → 60 u
120 of the earnings → 60 u ÷ 5 = 12 u
620 of the earnings → 6 x 12 u = 72 u
Number of orchids sold that contributed to the rest of the earnings
= 72 u ÷ 1 u
= 72
920 of the earnings → 9 x 12 u = 108 u
Number of peonies sold that contributed to the rest of the earnings
= 108 u ÷ 3 u
= 36
Number of flowers sold
= 9 + 17 + 72 + 36
= 134
Answer(s): 134
