Answer:
180
Step-by-step explanation:
This is a good question to keep in mind. When you do use a calculator the answer to this estimate will tell you if your work on the calculator is correct.
round the cost of the pizza to 10
18 * 10 = 180 dollars. So you should get an answer that is under 180 dollars -- about 3 dollars short. (0.17 * 18 which is another guess).
Now pick up your calculator and do the math. It comes to 176.94
If you do any grocery shopping, this is a good skill to have.
