To calculate Joe's take-home salary after deductions for income tax and savings, we'll follow these steps:
-
Start with the gross salary: $2,240.
-
Calculate the income tax deduction: \[ \text{Income tax} = 2,240 \times 0.18 = 403.20 \]
-
After deducting the income tax, the remaining salary is: \[ 2,240 - 403.20 = 1,836.80 \]
-
Now calculate the savings deduction from this remaining amount: \[ \text{Savings} = 1,836.80 \times 0.06 = 110.208 \]
-
Subtract the savings from the remaining salary: \[ 1,836.80 - 110.208 = 1,726.592 \]
So, Joe will take home approximately $1,726.59 after both deductions, not $1,702.40. Thus, the given answer of $1,702.40 is incorrect.
