Answer:
Belinda's profit is $3600, Candice's profit is $1200 and Diane's profit is $4800
Explanation:
Amy's ratio = 2
Amy's profit = $2400
Belinda's profit = (3/2) × $2400
= 3× $1200
= $3600
Candice's profit= (1 / 2) × $2400
= 1 × $1200
= $1200
Diane's profit = (4 / 2) × $2400
= 4 × $1200
= $4800
Total investment= [(2+3+1+4) / 2] × $2400
= (10 / 2) × $2400
= 10 × $1200
= $12000
