Answer: $500
Explanation:
The information provided suggests that Cindy made three donations:
1. $100 to United Way
2. $300 to the Canadian Cancer Society
3. $100 to the Green Party of Canada
To calculate the total amount she can claim on her tax return, add up these donations:
$100 + $300 + $100 = $500
So, Cindy can claim a total of $500 on her tax return for these donations.
