Aworker is paid $11/h plus and 8% commission on sales. what dollar amount in sales must the worker make to earn $300 in a 10-hour week?

11 per hrfor 10 hrs = 11 * 10 = 110
that means the worker made 300 - 110 = 190 on commission

so 8% of what is 190
.08x = 190
x = 190/.08
x = 2375 <=== worker has to make this in sales

check...
11(10) + .08(2375) =
110 + 190 = 300

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
