Cara’s total earnings in a month in which she sells $40,000 worth of merchandise is $ 4200
<h3><u>Solution:</u></h3>Given that Cara earns a base pay of $1,800 per month at a car dealership plus a commission of 6% of her sales
Let us first calculate commission earned from selling $40,000 worth of merchandise
commission earned from selling $40,000 = 6 % of $ 40,000
Also given that Cara earns a base pay of $ 1800 per month

<em>Cara’s total earnings in a month = base pay + commission earned</em>
Cara’s total earnings in a month = $ 1800 + $ 2400 = $ 4200
Thus the total earning of Cara in that month is $ 4200
