Sure! If the scooter costs $89.75 and there is a 7 1/4% sales tax, we can calculate the total cost by adding the tax amount to the original price.
To find the tax amount, we multiply the original price ($89.75) by the tax rate (7.25% or 0.0725).
Tax amount = $89.75 * 0.0725 = $6.51
Now, we can find the total cost by adding the original price and the tax amount:
Total cost = $89.75 + $6.51 = $96.26
So, with the sales tax included, the total cost of the scooter would be $96.26.
