Which term is defined as the dollar amount earned in a worker's paycheck?Dylan needs to compute his monthly gross pay. He earns $2,310 per month. Roman's Electronics pays him an 8.75% commission on his sales of $3,972. Calculate Dylan's gross pay.

The term for Total amount earned is GROSS pay.  What you actually get after deductions is NET pay (take-home pay)
Convert 8.75% to decimal form by dividing by 100 or simply moving decimal point 2 places to left (.0875)  Multiply that x sales ($3,792) to find commission and add that to $2,310 for GROSS pay.
