What is the total cost of a $2,099 couch including the 6.5% sales tax​
3241004551 [841]

The total cost of a $2,099 couch including the 6.5% sales tax​ is $ 2235.435

<u>Solution:</u>

Given that,

cost of couch = $ 2099

Sales tax = 6.5%

<em><u>Finding the total cost of couch with sales tax:</u></em>

Total cost of couch = selling price of couch + sales tax on the selling price of couch

Plugging in values we get,

<em>Total cost of couch = $ 2,099 + 6.5% sales tax on $ 2099</em>

\text { Total cost of couch }=2099+\frac{6.5}{100} \times 2099

Taking "2099" as common term, we get,

\text { Total cost of couch }=2099\left(1+\frac{6.5}{100}\right)

On solving brackets,

\text { Total cost of couch }=2099 \times 1.065=2235.435

Hence, the total cost of the couch is found as $ 2235.435

Line A is represented by the equation given below:
MrMuchimi
To have infinitely many solutions they must describe the same line.  So any multiple or fraction of the reference line would indeed describe the same line, and thus "intersect" at each and every of an infinite number of points.

2(x+y=4)

2x+2y=8  (is the same line as x+y=4)
