devlian [24]

Answer:

$7 200

Step-by-step explanation:

Amount of money paid for charity = $\frac{10}{100}$ × $22 000

= $2 200

Remaining money left for children = $22 000 - $2 200 - $10 800

= $9000

Let the amount of money her son receives be x and the amount her daughter gets be 4x.

Son's $ + Daughter's $ = $9000

x + 4x = 9000

5x = 9000

Amount of money her daughter gets (4x) = $\frac{4}{5}$ × 9000

= $7 200
