Your current biweekly gross salary is $1,343.77. You also earn a 7% commission on your monthly sales. If last month you sold $34,000 of product, determine your last month's gross salary pay. (Hint: Assume that there are two pay periods each month.)

Since the biweekly gross salary is $1,343.77, we multiply this value by 2 to determine the monthly gross salary. That is,

monthly gross salary = ($1343.77) x 2 = $2687.54

Then, add the 7% commission on sales amounting to $3,400.

commission = (0.07) ($3,400) = $238

Adding up the salary and the commission to get the monthly gross pay.

pay = $2687.54 + $238 = $2925.54
