Final answer:
Sophia needs to sell at least $16,744.19 in goods or services to make $1,800 with a 10.75% commission. We arrived at this figure by dividing the desired earnings by the commission rate after converting the percentage to a decimal.
Step-by-step explanation:
To calculate the minimum amount Sophia needs to sell to earn at least $1,800 with a 10.75% commission, we can use the following formula:
Total Sales = Desired Earnings / Commission Rate
Firstly, convert the percentage to a decimal by dividing by 100:
10.75% = 0.1075
Now, divide Sophia's desired earnings by the commission rate:
Total Sales = $1,800 / 0.1075
When we do the division, we find that Sophia needs to sell:
Total Sales = $16,744.19 approximately
This means Sophia needs to sell at least $16,744.19 worth of goods or services to meet her living expenses of $1,800 a month based on her commission rate.
