Question

Write an algebraic expression to model the price s of a pair of shoes plus 5% sales tax in simplest form

Answer 1

Let the cost of pair of shoes is x.

So we can get price s by adding cost and sales tax.

Sales tax = 5% of cost
=
`(5*x)/(100) = (x)/(20)`

So the price of pair of shoes is modeled as given below


`s = x + (x)/(20)`


`s = (20x + x)/(20)`


`s = (21x)/(20)`
