C step-by-step the coordinate of that is pretty simple to say but hard at the same time
Answer:
(a) 305 visitors (b): Saturday to Sunday
Start with hours worked 6 x $9 = 54
Then commission $700 x 0.12 (12% converted to a decimal) = $84
Add up 54 + 84 = $138 total income
So answers are A, the first C (you make $84 in commission), and the last one, you make $138 in total.
