Question

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.
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
Rhea worked 15 hours last week and made $260 in total. What were her total sales in computers for the week?
Why do you think employers offer commissions to their employees? Do you think there are any potential problems with this form of earnings?

Answer 1

Answer:

d) E = 8h + 0.05s

Her total sales in computers for the week is $2800.

Step-by-step explanation:

Let Rhea's hourly pay =h

She makes $8/hour, therefore sales for h hours =$8h

Let the volume of sales = s

She also earns 5% commission on sales = 5% of s = 0.05s

Therefore, the expression which best describes Rhea's total earnings:

(D) E=8h+0.05s

Rhea worked 15 hours last week and made $260 in total.

h=$15

From the formula

260=8(15)+0.05s

0.05s=260-8(15)

0.05s=140

s=2800

Her total sales in computers for the week is $2800.

Employers offer commissions to their employees to motivate them to seek to make sales rather than just passing time.

In so far as the sales commission do not eat up the profit of the business,  there are no potential problems with this form of earnings
