38 of them were plums,
13 of the remainder were dragon fruits and the rest were pomegranates. The amounts earned for each plum, each dragon fruit and each pomegranate sold are $1.40, $1.80 and $1.20 respectively. The number of plums sold to the number of dragon fruits sold to the number of pomegranates sold was 4 : 3 : 2. In total, she sold
14 of the fruits and earned $214.40. How many plums did she have at first?

Total amount that Cindy earned
= 5.6 u + 5.4 u + 2.4 u
= 13.4 u
13.4 u = 214.40
1 u = 214.40 ÷ 13.4 = 16
Total number of fruits sold
= 4 u + 3 u + 2 u
= 9 u
= 9 x 16
= 144
Total number of fruits at first
= 144 ÷
14= 144 x 4
= 576
Total number of fruits at first
= 9 p + 5 p + 10 p
= 24 p
24 p = 576
1 p = 576 ÷ 24 = 24
Number of plums that Cindy had at first
= 9 p
= 9 x 24
= 216
Answer(s): 216
