Question

Allison went to the store with friends. she spent $2.90 on pencils,$4.39 on paper,and $5.78 on pens. Estimate how much money Allison spent.

Answer 1

2.90 is close to 3 so round it up to 3.

4.39 rounds down to 4 dollars because it is less than 4.50.

5.78 rounds up to 6 dollars because it is greater than 5.50.

3+4+6=13 dollars

Answer 2

13.70$ would be the answer.

I estimated like the problems say, so if you need an exact answer just comment. :)
