Question

Patrick is buying a new pair of shoes. The expression shown below represents the sales tax on the price of the shoes, s. 0.06s By what number can Patrick multiply the price of the shoes, s, to determine the total amount he will need to pay for them, including the tax?

Answer 1

The total amount that Patrick needs to pay for the shoes including the tax is equal to sum of price, s and the tax, 0.06s. Mathematically, this can be expressed as,
                                 total price = s + 0.06s
Simplifying the equation,
                              total price = 1.06 s
Therefore, Patrick can multiply the price of the shoes, s by 1.06.
