Answer 1

Answer:

$ 7320

Step-by-step explanation:

With optional equipment, an automobile cost $9120. If the cost of the basic car is $120 more than 4 times the price of the optional equipment, what was the cost of the basic car?

Let say cost of optional equipment = $ E

Cost of the Basic car = 4E + 120  $

Cost of car with optional equipment = E + 4E + 120 $

= 5E + 120 $

5E + 120 = 9120

=> 5E = 9000

=> E = 1800

Cost Of basic Car = 4E + 120 = 4 * 1800 + 120 = $ 7320
