A) $ 3000

Step-by-step explanation:

Here, dealership purchased a four-door sedan for $15,000 and then sold it at 15% markup.

Thus, his profit in this sedan = 15 % of $15000 = = $ 2250

And, The dealership paid the buyer $3000 for a trade-in, which was sold the following week at 25% markup.

Thus, his profit in this deal = 25 % of 3000 = = $ 750

The dealership's profit on these two vehicles =  $ 2250 + $ 750 = $ 3000

Thus, Option A is correct.

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..
