Answer 1

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Number of cars sold in first month = 4900

Sales drop by 100 cars per month for the first year:

A(x) = a - 100(x - 1)

No = sale In first month = 4900

First five months

Ist month :

a = 4900

2nd :

4900 - 100 = 4800

3rd :

4800 - 100 = 4700

4th:

4700 - 100 = 4600

5th:

4600 - 100 = 4500

First five terms : (4900,4800,4700,4600, 4500)

Predicted sales for 12th month :

A(12) = 4900 - 100(12 - 1)

A(12) = 4900 - 1100

= 3800

Total sales for the first year:

4900+4800+4700+4600+4500+4400+4300+4200+4100+4000+3900+3800) =

= 52,200
