For this case we have the following variable:
s: The price of a pair of shoes
Therefore, the 5% sales tax is given by:
[tex] (\frac{5}{100}) s [/tex]
Then, the complete expression is:
The price of a pair of shoes plus 5% sales tax.
Writing algebraically we have:
[tex] s + (\frac{5}{100}) s [/tex]
Simplifying we have:
[tex] s + 0.05s [/tex]
[tex] s (1 + 0.05) [/tex]
[tex] 1.05s [/tex]
Answer:
an algebraic expression to model the given context is:
[tex] 1.05s [/tex]
