23 of the remainder were mandarin oranges and the rest were tomatoes. The amounts earned for each apricot, each mandarin orange and each tomato sold are $1.20, $1.90 and $1.40 respectively. The number of apricots sold to the number of mandarin oranges sold to the number of tomatoes sold was 4 : 5 : 3. In total, she sold

Total amount that Jean earned
= 4.8 u + 9.5 u + 4.2 u
= 18.5 u
18.5 u = 203.50
1 u = 203.50 ÷ 18.5 = 11
Total number of fruits sold
= 4 u + 5 u + 3 u
= 12 u
= 12 x 11
= 132
Total number of fruits at first
= 132 ÷
13= 132 x 3
= 396
Total number of fruits at first
= 3 p + 4 p + 2 p
= 9 p
9 p = 396
1 p = 396 ÷ 9 = 44
Number of apricots that Jean had at first
= 3 p
= 3 x 44
= 132
Answer(s): 132
