Evelyn sells used cars he base salary is $800 a week and she receives a 12% commission on each sale represent Evelyn total salary for the week if she had d dollars of sales

800 + 0.12d

8.12

To calculate Evelyn's total salary for the week, we need to add her base salary of $800 to her commission on sales.

The commission on sales can be calculated by multiplying the sales amount (d dollars) by the commission rate of 12% (0.12).
Commission on sales = (d dollars) x 0.12

Total salary for the week = Base salary + Commission on sales
Total salary for the week = $800 + (d dollars x 0.12)

So Evelyn's total salary for the week, with d dollars of sales, would be $800 + (d x 0.12) dollars.

To calculate Evelyn's total salary for the week, you will need to determine the commission earned from the sales and add it to her base salary.

To find the commission earned, you can multiply the sales amount (d dollars) by the commission rate (12% or 0.12). This will give you the commission amount.

Commission = d dollars * 0.12

Next, you need to add the commission amount to Evelyn's base salary:

Total Salary = Base Salary + Commission

Total Salary = $800 + Commission

Therefore, Evelyn's total salary for the week, if she had d dollars of sales, would be $800 + Commission, where Commission = d * 0.12.
