4. Rhea obtained a CO-OP credit working at a computer store. They have now hired her for a summer job with the store. She makes $8/hour, plus a 5% commission on sales.

i Which expression best describes Rhea's total earnings? Explain.
a) E = 8h + 5s b) E= 8h + 50s
C) E = 8h +.005s d) E= 8h +0.05s

ii. Rhea worked 15 hours last week and made $260 in total. What were her total sales in computers for the
week?

iii. Why do you think employers offer commissions to their employees? Do you think there are any potential
problems with this form of earnings?

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
