Question

A shopper wants to ensure he has enough cash to purchase a $33 encyclopedia, so he asks a clerk what the total will be with the sales tax included. The clerk tells him the total will be $34.65. What is the sales tax percentage?
My answer is .05 which is 5%. Am I correct?

Answer 1

$\huge\boxed{5\%}$

First, divide with a calculator.

$34.65\div 33=1.05$

Now subtract $1$, which is equivalent to the value of the item, as it is equal to $100\%$.

$1.05-1=0.05$

Move the decimal two places to the right to convert it to a percentage.

$0.05\longrightarrow\large\boxed{5}$
