Anthony Walker started a snow removal business he called Sandhill Services. Over the fall months, Sandhill pre-sold snow removal services to be performed from November through April of the following fiscal year, inclusive. If payment is made in full by November 1, a 10% discount is allowed. In October, 300 customers took advantage of the discount and purchased the winter snow removal service package priced at $500 each, before the discount. Due to the heavy snowfall, another 355 customers purchased the package for $600 each in December, and in January, another 220 purchased it for the reduced price of $550 each. Calculate the amounts for each of the three groups of payments, and insert in the following table for each month the amount of revenue to be recognized by Sandhill, as well as totals. Assume that the amount of revenue is allocated evenly over the months of service. (Do not leave any answer field blank. Enter O for amounts.)
