What is the equation that represents the sequence in this problem ? Find the price after the 8th month

AVprozaik [17]

ANSWER

$\begin{gathered} a_n=ar^{n\text{ - 1}} \\ a_8\text{ = \$38.26} \end{gathered}$

EXPLANATION

The problem represents a geometric progression.

The general form of a geometric sequence is:

$a_n=ar^{n\text{ - 1}}$

where a = first term

r = common ratio

The first term from the table is the first price (for the first month). That is $80.00

To find the common ratio, we divide a term by its preceeding term.

Let us divide the price of the second month from the first.

We have:

$\begin{gathered} r\text{ = }\frac{72}{80} \\ r\text{ = 0.9} \end{gathered}$

The price after the 8th month is the value of a(n) when n = 8

So, we have that:

$\begin{gathered} a_8\text{ = 80 }\cdot0.9^{(8\text{ - 1)}} \\ a_8\text{ = 80 }\cdot0.9^7 \\ a_8\text{ = \$38.26} \end{gathered}$

Please I need help with this problem number 5????

zheka24 [161]

Estimating the area:
$x = (20 \times 8)(13 \times 8) \\ x = 264$
Calculating wallpaper:
$x = (264 \times 1.05) \div 35 \\ x = 7.92 \\ x = 8$
we round up here because they will need a full roll to complete the room. Since they can't buy 7.92 rolls, they must buy 8.

Calculating cost:
$x = 8(31.48) + 31.48(0.0825) \\ x = 254.44$
