Final answer:
a. x + 0.08x. The algebraic expression to model the given context is: x + 0.08x. To find the price of a pair of shoes plus 8% sales tax, you need to add the original price (x) to 8% of the original price (0.08x). This can be simplified to x + 0.08x, which gives the total price including sales tax.
Step-by-step explanation:
The algebraic expression to model the given context is: x + 0.08x.
To find the price of a pair of shoes plus 8% sales tax, you need to add the original price (x) to 8% of the original price (0.08x). This can be simplified to x + 0.08x, which gives the total price including sales tax.
For example, if the original price of the shoes is $100, the expression would be 100 + 0.08(100). Solving this gives $108, which is the final price including sales tax.
