Answer: Option(e) exist 123.50 is correct.
Explanation:
James earns:
Product A: 15 × 35.75 = 536.25
Product B: 16 × 42.25 = 676
Total Earnings = 1212.25
Sally earns:
Product A: 25 × 35.75 = 893.75
Product B: 10 × 42.25 = 422.5
Total Earnings = 1316.25
Andre earns:
Product A: 18 × 35.75 = 643.5
Product B: 13 × 42.25 = 549.25
Total Earnings = 1192.75
Above calculation shows that Sally is the most profitable seller and Andre is the least profitable seller.
So, the difference between the most profitable seller i.e Sally (1316.25) and the least profitable seller i.e. Andre (1192.75) is 123.50.
