B $940$940
C $370$370
D $480$480

Answer 1

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.
