If pizzas cost $9.83 per pizza, estimate how much money you would need to buy 18 of them.

your answer does not need to be exact, so do not use a calculator and do not put a $ sign in your 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.

x=6 and x=3
