Please explain to me how I can do this .Sarah works in an appliance store. She gets a commission in addition to her hourly pay. She earns a 4%
commission for sales up to $4000 and a 7% commission for all sales in a month above $4000. Last
month her sales were $5300. How much was her commission?

To calculate Sarah's commission, we need to determine two things: the total sales and the commission rate.
First, let's find the total sales. We know that Sarah's sales last month were $5300.
Next, let's determine the commission rate. According to the information provided, Sarah earns a 4% commission for sales up to $4000 and a 7% commission for all sales above $4000.
To calculate the commission, we need to split the total sales into two parts: the sales up to $4000 and the sales above $4000.
Step 1: Calculate the commission for sales up to $4000:
Commission = Total sales up to $4000 * Commission rate for sales up to $4000
Commission = $4000 * 4% = $160
Step 2: Calculate the commission for sales above $4000:
Commission = Total sales above $4000 * Commission rate for sales above $4000
Commission = ($5300 - $4000) * 7% = $1300 * 7% = $91
Step 3: Calculate the total commission:
Total commission = Commission for sales up to $4000 + Commission for sales above $4000
Total commission = $160 + $91 = $251
Therefore, Sarah's commission for last month's sales of $5300 would be $251.
