Cara earns a base pay of $1,800 per month at a car dealership plus a commission of 6% of her sales. What are Cara’s total earnin
k0ka [10]

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

\text {commission earned from selling } \$ 40,000=\frac{6}{100} \times 40,000

\text {commission earned from selling } \$ 40,000=2400

Also given that Cara earns a base pay of $ 1800 per month

So Cara’s total earnings in a month in which she sells $40,000 worth of merchandise is calculated by adding commission earned $ 2400 to base pay $ 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

#!). Two planes leave New York at 10am, One heading for Europe at 600mph and one heading in the opposite direction at 150mph. At
timurjin [86]

Speed = Distance / time

Distance = Speed x time

In t hours, first plane travels = 600 t miles

In t hours, the second plane travels =150 t miles

After t hours the distance between the two planes is:

(600t+150t)= 750t ( since both travel in opposite directions)

When the distance is 900 miles:

750t= 900

Solve for t:

t= 900/750

t= 1.2 hours

After 1.2 hours.

1.2 x 60 = 72 minutes = 60 +12 = 1 hour and 12 minutes

Since both leave at 10 pm:

10am + 1 hour and 12 minutes : 11:12 am

They will be 900 miles apart at 11:12 am

Each one traveled:

Plane 1:

Distance: Speed x time = 600 mph x 1.2 = 720 miles

Plane 2:

Distance = Speed x time = 150 mph x 1.2 = 180 miles
