Rob sells electronics and earns $625 per week, plus 12% of his sales. Last week, he sold $3250 worth of electronics. What was his total earnings for last week?

$1,015

Step-by-step explanation:

Given that:

Weekly earning = $625

Commission = 12% of sales

sales made last week = $3250

Last week earning = weekly earning + commision on sale

Commission on sale = 12% of sales

Commission on sale = (0.12 * 3250) = $390

Last week earning = weekly earning + commision on sale

Last week earning = $625 + $390 = $1,015

the answer is b.)
