Question

What is the algebraic expression of the price of a video game system plus 9% sales tax

Answer 1

Step-by-step explanation:

Given;

We are given the price of a video game system plus a 9% sales tax.

Required;

We are required to find an algebraic expression to represent the above condition.

Step-by-step solution;

The price is yet unknown. Therefore let the price be represented by x.

Also the sales tax is given as 9% which in decimal would be 0.09, that is;

`9\%=(9)/(100)=0.09`

The price plus the sales tax therefore would be;

`\begin{gathered} Price=x \\ Sales\text{ }tax=0.09* x \\ Sales\text{ }tax=0.09x \end{gathered}`
`Price+sales\text{ }tax=x+0.09x`

ANSWER:

`x+0.09x`
