To estimate how much Preston will earn if he works 5 days, we can take the average of the minimum and maximum amounts he earns per day.
Average daily earnings = (Minimum daily earnings + Maximum daily earnings)/2
= ($64 + $81)/2
= $145/2
= $72.50
So, a reasonable estimation of how much Preston will earn if he works 5 days is $72.50 * 5 = $362.50.
Among the given options, the closest estimation is C) $370.
To find a reasonable estimation of how much Preston will earn if he works 5 days, we can find the average of the minimum and maximum values.
The average of $64 and $81 is $(64 + 81) / 2 = 72.5.
Now, multiply the average daily earnings by the number of days Preston works: $72.5 \times 5 = 362.5.
Since we are rounding to the nearest whole number, the reasonable estimation of how much Preston will earn if he works 5 days is $370.
Therefore, the correct answer is C. $370.
To estimate how much Preston will earn if he works 5 days, we need to find the average amount he earns per day and then multiply it by the number of days he works.
First, we find the average daily earnings by adding the minimum and maximum amounts he earns and dividing it by 2:
(64 + 81) / 2 = 145 / 2 = 72.5
Now, we multiply the average daily earnings by the number of days he works:
72.5 * 5 = 362.5
Therefore, a reasonable estimation of how much Preston will earn if he works 5 days is $362.50.
However, the given answer choices are not in decimal format, so we need to round it to the nearest whole dollar. In this case, the closest whole dollar would be $363.
Therefore, the correct answer is not provided in the given options.
