Answer:
$560
Step-by-step explanation:
You want to know how much less X receives if the profit of $4800 is shared equally than if the profit is shared in proportion to the investments: X, $9000; Y, $7000; and Z, $4000.
Proportional
The profit X receives if proportional to the investment is ...
$4800 × 9000/(9000 +7000 +4000) = $4800(9/20) = $2160
Equal division
The profit X receives if divided equally is ...
$4800 / 3 = $1600
Less
The amount X receives from equal division is ...
$2160 -1600 = $560
less than from division proportional to investment.
