Jaslyn had some fruits at her stall.
38 of them were apricots,
13 of the remainder were papayas and the rest were dragon fruits. The amounts earned for each apricot, each papaya and each dragon fruit sold are $1.50, $1.90 and $1.40 respectively. The number of apricots sold to the number of papayas sold to the number of dragon fruits sold was 3 : 5 : 2. In total, she sold
16 of the fruits and earned $100.80. How many apricots did she have at first?

Total amount that Jaslyn earned
= 4.5 u + 9.5 u + 2.8 u
= 16.8 u
16.8 u = 100.80
1 u = 100.80 ÷ 16.8 = 6
Total number of fruits sold
= 3 u + 5 u + 2 u
= 10 u
= 10 x 6
= 60
Total number of fruits at first
= 60 ÷
16= 60 x 6
= 360
Total number of fruits at first
= 9 p + 5 p + 10 p
= 24 p
24 p = 360
1 p = 360 ÷ 24 = 15
Number of apricots that Jaslyn had at first
= 9 p
= 9 x 15
= 135
Answer(s): 135
