Andy buys a computer that cost $575. the sales tax is 5%. describe a method he could use to estimate the sales tax. will the estimated tax be greater or less than the actual tax.

Multiply 575 by .05 to find the sales tax. then add it to 575 to find the total amount he needs to pay. the tax will be around it, we have no way of knowing whether it is greater or less than the actual tax.

PS: the answer is $603.75 for the computer and tax.

What do you mean i don’t understand
