Last week, you worked a total of 43 hours, and your boss’s assistant calculated your mean hourly salary using the expression . 15.79 x 40 + 25.80 / 43

What mistake did your boss’s assistant make?
Your boss’s assistant should have divided by 2.
Your boss’s assistant should have divided by 41.
Your boss’s assistant should have multiplied 25.80 by 3.
Your boss’s assistant should have just added 15.75 and 25.80.
Your boss’s assistant should have divided by 40.

Answer 1

Your boss’s assistant should have multiplied 25.80 by 3.
