What is 19a-3(a-6)=78

Ivan

Answer:

a = 3.75

Step-by-step explanation:

First distribute the -3 to (a - 6), which gives you the equation, 19a - 3a + 18 = 78. Then subtract the 3a from 19a, which gives you 16a + 18 = 78. Then subtract 18 from both sides and you get 16a = 60. Divide 60 by 16 and you get 3.75 as your a.

The best buy is from dealership A because the fees of dealership B is more expensive

<h3>The add-on options</h3>

For the purpose of this exercise, the add-on options to select are:

Air-conditioning
Sunroof
GPS
Bluetooth
Power door and window

<h3>Dealership A</h3>

The total amount of the add-on options is:

Total = $1000 + $500 + $3500 + $500 + $750

Total = $6250

<u>The inequality</u>

This is represented using:

Base price * (1 + Tax) + Fees + Add-on total ≤ 20000

So, we have:

(1 + 6.75%) * x + 751.56 + 6250 ≤ 20000

<u>Solve for x</u>

We have:

(1 + 6.75%) * x + 751.56 + 6250 ≤ 20000

Evaluate the like terms

(1 + 6.75%) * x ≤ 12998.44

Divide both sides by (1 + 6.75%)

x ≤ 12176.52

The solution means that the base price of the car cannot exceed $12176.52 for dealership A

<h3>Dealership B</h3>

The total amount of the add-on options is:

Total = $500 + $750 + $2750 + $750 + $500

Total = $5250

<u>The inequality</u>

This is represented using:

Base price * (1 + Tax) + Fees + Add-on total ≤ 20000

So, we have:

(1 + 6.75%) * x + 1524.72 + 5250 ≤ 20000

<u>Solve for x</u>

We have:

(1 + 6.75%) * x + 1524.72 + 5250 ≤ 20000

Evaluate the like terms

(1 + 6.75%) * x ≤ 13225.28

Divide both sides by (1 + 6.75%)

x ≤ 12389.02

The solution means that the base price of the car cannot exceed $12389.02 for dealership B
