Respuesta :

Answer:

1. E = 8h + 0.05s

2. $2,800

3. please check explanations

Step-by-step explanation:

Firstly, we need an expression for what she earns.

The key to answering this is to know that 5% is same as 5/100 = 0.05

So , if her total sales is given as S, the amount she makes as commission would be 0.05s

So the Total earnings given that she works h hours per week and earns $8/h is $8h

So total earnings E = 8h + 0.05s

Now we want to get to total sales given she worked 15 hours last week and earned $260 in total.

What this means is that we have h and E and we want to find s for that week.

What we need to do is to plug the values into the equation we have defined above;

Thus;

260 = 8(15) + 0.05s

260 = 120 + 0.05s

0.05s = 260-120

0.05s = 140

s = 140/0.05

s = $2,800

I think employers offer commission to serve as a form of morale booster which helps to make their employees work better by sustaining their enthusiasm on the job and also augment their salaries

No, I do not think there are potential problems
