If $2300 is spent on vacations or travel each year, estimate how much should be set aside each month for those expenses? a. approximately $200 per month should be set aside for vacation or travel expenses. b. approximately $2300 per month should be set aside for vacation or travel expenses. c. approximately $1250 per month should be set aside for vacation or travel expenses. d. approximately $230 per month should be set aside for vacation or travel expenses.

Remember that an estimate is a quick and simplified calculation. When you are estimating something, you round numbers to the nearest tenth or hundredth in order to simplify calculations and give a quick answer.

We know that $2300 is spent on vacations or travel each year, and we want to estimate how much should be set aside each month for that expense.

Notice that 1 year has 12 months, so the precise calculation is $2300 ÷ 12, which is difficult to calculate quickly, so instead of the precise answer, we are going to give an estimate. To estimate we are going to round 12 to 10, so the new simplified calculation is $2300 ÷ 10, which is very easy to calculate; in fact, we just need to drop a zero from $2300 to get the estimate $230.

We can conclude that the correct answer is d. Approximately $230 per month should be set aside for vacation or travel expenses.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
