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.
A more reasonable estimate would be 15.
The best estimate is always the exact answer since it is always possible to improve upon any other estimate.
The front end estimate is 1000. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 1374 to 1 trillion, I would estimate it as 0. If I had to add 1374 to 0.0000000001, I would use the number as given - not use an estimate.Also,if I had to calculate 1374/13 I might estimate it by 1365 because 1365/13 = 105 can be calculated mentally.
150 - 4000 - 600 = -4450
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.
