Final answer:
Susan saves 17.6% of her monthly net income and spends 82.4%.
Step-by-step explanation:
To calculate the percentage of Susan's monthly income that she saves, we divide the amount saved by the total income and then multiply by 100:
Savings percentage = ($330 ÷ $1875) × 100 = 17.6%
Therefore, Susan saves 17.6% of her monthly income.
Next, to find out what percentage of her monthly income Susan spends, we subtract the savings percentage from 100%:
Spending percentage = 100% - 17.6% = 82.4%
Susan spends 82.4% of her monthly net income.
