Final answer:
Without the weekly sales amounts, it's impossible to calculate Jack's total commission over the four-week period. More information is needed to determine the correct answer from the provided options.
Step-by-step explanation:
The question asks us to calculate the total commission Jack made over four weeks at a sporting goods store. Unfortunately, the amount Jack sold each week, which is essential for determining his commission, is not provided in the question. Without the sales amounts for each of the four weeks, we cannot calculate Jack's total commission. Thus, we cannot determine whether answer options A. $200.00, B. $260.00, C. $2000.00, or D. $2600.00 are accurate.
If we had the total sales amounts for each week, we could multiply each week's total sales by Jack's commission rate of 20% to find the weekly commission. Adding up all four weeks' commissions would give us the total commission for the month.
