Dan Works On Commission And Earns 4% On All Sales

Dan Works On Commission And Earns 4 On All Of His Sales In Month 1

Dan works on commission and earns 4% on all of his sales. In month 1, he sold $25,000; month 2 was $17,000; and month 3 was $34,000. 18% of his total earnings are taken out for taxes. Calculate the total net (after taxes) pay Dan earned over the 3 months. Write and simplify an expression that represents this scenario.

Paper For Above instruction

The scenario involves calculating Dan's total earnings over three months based on his commission rate, followed by deducting taxes to determine his net income. To solve this problem systematically, we need to first determine his gross earnings from sales in each month, then compute the total gross earnings, and finally subtract taxes to arrive at the net earnings.

Initially, Dan earns 4% of his sales each month. For each month, his earnings are obtained by multiplying his monthly sales by 0.04 (since 4% is equivalent to 0.04). Specifically:

- Month 1: $25,000 * 0.04 = $1,000

- Month 2: $17,000 * 0.04 = $680

- Month 3: $34,000 * 0.04 = $1,360

Next, calculate the total gross earnings over the three months:

Total Gross Earnings = $1,000 + $680 + $1,360 = $3,040

Since 18% of his earnings are deducted for taxes, calculate the total taxes:

Tax amount = 18% of $3,040 = 0.18 * $3,040 = $547.20

Subtract the taxes from the gross earnings to find the net pay:

Net pay = Total Gross Earnings - Taxes = $3,040 - $547.20 = $2,492.80

For an algebraic expression, let \( S_1, S_2, S_3 \) represent Dan's monthly sales:

- Monthly earnings: \( 0.04 \times S_i \) for i=1,2,3

- Total gross earnings: \( 0.04 (S_1 + S_2 + S_3) \)

- Total taxes at 18%: \( 0.18 \times 0.04 (S_1 + S_2 + S_3) \)

- Total net pay: \( \left[ 0.04 (S_1 + S_2 + S_3) \right] - \left[ 0.18 \times 0.04 (S_1 + S_2 + S_3) \right] \)

Simplify the expression:

Total net pay = \( 0.04 (S_1 + S_2 + S_3) \times (1 - 0.18) = 0.04 \times 0.82 \times (S_1 + S_2 + S_3) \)

Substituting back the specific sales:

Total net pay = \( 0.04 \times 0.82 \times (25,000 + 17,000 + 34,000) \)

Calculating the sum:

\( 25,000 + 17,000 + 34,000 = 76,000 \)

Final simplified expression:

Total net pay = \( 0.04 \times 0.82 \times 76,000 = 0.0328 \times 76,000 \)

Calculating the final amount:

Total net pay = \$2,492.80

This approach provides a clear mathematical method to determine Dan's net earnings over three months, accounting for commissions and taxes.
