Question

Roy buys a coat for $86.40 which includes An 8% sales tax which equation could you use to find the cost of the coat, c, without the Sales tax

Answer 1

Answer:

86.40  =  c  + 0.08 c  is the equation which can be used to find the cost of the coat, c, without the Sales tax

Step-by-step explanation:

Let us assume the cost of the coat = c

Selling price of coat = $86.40

The sale tax on the coat = 8%

⇒ The sale tax = 8% of c

Calculating the sales tax, we get:

$\frac{8}{100}  \times  = 0.08 c$

or, the sales tax amount on the cost price of coat = 0.08 c

Now, the Sales Price of coat =Cost Price of Coat + sales Tax Amount

⇒ $86.40  =  c  + 0.08 c

Hence,  86.40  =  c  + 0.08 c  is the equation which can be used to find the cost of the coat, c, without the Sales tax.
