Karen earns a weekly gross salary of $628. Tax of $148.90 is deducted. 4.5% is paid into a superannuation fund a 8% is paid directly towards mortgage. Karen aims to save 10% of her remaining income. What amount will she save each week?

If the %ages are based on the gross, then she saves

(628-148.90-628(.045+.08))*.10 = $40.06

If they are based on after-tax income, then she saves

(628-148.90)(1-(.045+.08)))*.10 = $41.92

To find out how much Karen will save each week, we need to calculate her remaining income after deducting taxes, superannuation, and mortgage.

1. Subtract tax from the gross salary: $628 - $148.90 = $479.10
2. Subtract the superannuation contribution: $479.10 - (4.5% * $479.10) = $479.10 - $21.56 = $457.54
3. Subtract the mortgage payment: $457.54 - (8% * $457.54) = $457.54 - $36.60 = $420.94
4. Calculate the amount Karen will save: 10% * $420.94 = $42.09

Therefore, Karen will save $42.09 each week.

To calculate the amount Karen will save each week, we need to break down her income and deductions step by step.

1. Start with the gross salary: $628
2. Deduct the tax amount: $628 - $148.90 = $479.10
3. Deduct the superannuation fund contribution: $479.10 - (4.5% of $479.10)
= $479.10 - (0.045 * $479.10) = $479.10 - $21.56 = $457.54
4. Deduct the mortgage payment: $457.54 - (8% of $457.54)
= $457.54 - (0.08 * $457.54) = $457.54 - $36.60 = $420.94

Now, Karen aims to save 10% of her remaining income after all the deductions:

Amount to save = 10% of $420.94
= 0.10 * $420.94
= $42.094

So, Karen will save approximately $42.09 each week.
