Answer:
Percentage = 28.57%
Explanation:
Jane had $70 and spent $30 on stationery and $20 on chocolates. Therefore, she spent a total of $30 + $20 = $50 on these items.
She donated the rest of the money, which is $70 - $50 = $20, for flood victims.
To find the percentage of money given by Jane for donation, we can use the following formula:
Percentage = (Part / Whole) x 100%
where the "Part" is the amount donated by Jane and the "Whole" is the total amount of money she had, which is $70.
Percentage = ($20 / $70) x 100%
Percentage = 28.57%
Therefore, Jane gave 28.57% of her money for donation to flood victims.
