To mentally estimate the total cost of these items, we would substitute the following numbers 2, 1, 3.5, 10, and 6. By rounding to the half-dollar, the estimate would be 22.5. This assumes that the 98 is a 98-cent item. If it were a 98-dollar item, the estimate would be 119.5.

Oh, what a happy little question! To estimate 650 divided by 8, you can round 650 down to 640. Then, divide 640 by 8, which is 80. This gives you a close estimate that is easier to work with mentally. Just remember, there are no mistakes in estimating, just happy little accidents!
Compatible numbers can easily be divided mentally.
It's $22.50.

A person would need to know what all of the following prices are to know what the total cost would be. It is important that this information is included along with the full question so the correct answer will be able to be given.

rounding
Estimating 26 plus 78 as 25 plus 75 is a form of rounding that simplifies the calculation while maintaining the overall magnitude of the numbers involved. By rounding down to 25 and 75, you are working with numbers that are easier to mentally add together quickly. This estimation technique is particularly useful when you need a rough answer or when exact precision is not necessary.

A point arguing that most teen criminals are fully developed mentally and socially would not be able to fit under the subtopic "most teen criminals not fully developed mentally and socially."
