Answer:
111
Step-by-step explanation:
NP = (S x 1.10) - 10
OP = NP / .9
(5x^3 + 3x^2 + 5x) + (7x^3 -3x^2 +8x) = (12x^3 + 13x)
(3x^3 + 5x^2 + 4x) + (9x^3 - 5x^2 + 9x) = (12x^3 + 13x)
Yesterday's closing price was 7.25.
In order to find this, we take the current price and subtract how much it went up. This will give us the price from before it rose.
7.375 - .125 = 7.25
The first five terms of the sequence are; 4,600, 4,550, 4,500, 4,450, 4,400 and the total predicted number of sold cars for the first year is 51,900 cars
<h3>Arithmetic sequence</h3>
- First month, a = 4,600 cars
- Common difference, d = -50 cars
First five terms;
a = 4,600
a + d = 4600 + (-50)
= 4600 - 50
= 4,550
a + 2d
= 4600 + 2(-50)
= 4600 - 100
= 4,500
a + 3d
= 4,600 + 3(-50)
= 4,600 - 150
= 4,450
a + 4d
= 4600 + 4(-50)
= 4,600 - 200
= 4,400
cars predicted for the twelfth month.
a + 11d
= 4600 + 11(-50)
= 4600 + 550
= 4,050
Total predicted number of sold cars for the first year:
Sn = n/2{2a + (n - 1)d }
= 12/2{2×4600 + (12-1)-50}
= 6{9200 + 11(-50)}
= 6(9,200 - 550)
= 6(8,650)
= 51,900 cars
