Mark works at a popular electronics retail store. he earns a fixed income of $18 an hour and a 5% commission on the sales he makes. let's say, y = earnings h = number of hours worked s = amount of sales which of these equations correctly indicates how much mark earns in a day?

Mark earns in a day is y = 18h + 0.05s .

Step-by-step explanation:

As given

Mark works at a popular electronics retail store.

He earns a fixed income of $18 an hour and a 5% commission on the sales he makes.

As given

y = earnings .

h = number of hours worked

s = amount of sales

5% is written in the decimal form.

= 0.05

Mark earns through commission = 0.05 × s

                                                      = 0.05s

Mark earns h working hours = 18h

Thus

Total earning of the mark = Mark earns h working hours  + Mark earns through commission .

Put the value

y = 18h + 0.05s

Therefore the Mark earns in a day is y = 18h + 0.05s .
