The money that she makes is $225.
Given that,
- She purchased 20 pearl for $500.
- She sold three-fourth at $40 each.
- And, the rest should be sold at the cost price.
Based on the above information, the calculation is as follows:
Since 20 pearls are purchased for $500
So one pearl should be
[tex]= \frac{500}{20}[/tex]
= $25
Now three-fourth of 20 should be 15
And, its price should be
[tex]= 15\times \$40[/tex]
= $600
And, the remaining is
[tex]= 5 \times \$25[/tex]
= $125
So, the total is
= $600 + $125
= $725
Now the money she make is
= $725 - $500
= $225
Therefore we can conclude that the money that she makes is $225.
