Lara uses a calculator to figure out the total cost of a $23 blender. Including sales tax, the total is $24.38. What is the sales tax percentage?

Write your answer using a percent sign (%).

The sales tax is $24.38 - $23 = $1.38.

To find the sales tax percentage, we divide the sales tax amount by the original cost of the blender:

($1.38 / $23) x 100 = 6%

Therefore, the sales tax percentage is 6%.
