The amount due for the first term of payment is the product of the total sales and the percentage.
(1) Amount due = ($85,000)(0.04) = $3,400
The total amount due for the second term of payment is the product of the total sales and the percentages together with all the fees specified in the item (insurance, maintenance, and utilities).
(2) Amount due = ($85,000)(0.03) + $175 + $50 + $345 = $3,120
If we are to compare the two amounts, using the second term of payment, lesser amount will be paid. Thus, the answer to this item is the second choice.
