Logan bought a book. The tax rate was 7%. How do you write 7% as a decimal in order to multiply?

• 0.7

• 7.0

• 0.07

Answer explanation

PER cent - out of a hundred - HUNDREDTHS. The percent should go to the hundredths place!!! Two places behind the decimal!

When you are finding sales tax, you first multiply the tax (in decimal form) times the cost of the item...then what?

• Then multiply again.

• Then add that amount to the original cost.

• Then subtract that amount from the original cost.

• Then do nothing - you're done.

Answer explanation

PLEASE DON"T MISS THIS!!!

After you multiply the percent (as a decimal) by the original cost...you MUST ADD the new amount to the original amount!!!!!! You are adding the tax to the cost of the item. Do not just leave it at the tiny tax cost!
