Question

An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale. Let A be the amount of the sale in dollars and C be the charge of the online auction. Explain whether the solutions A=−5 and C=1.1 are viable. (1 point)

A. The solutions are viable because the amount charged is positive.

B .The solutions are not viable because the amount of the sale cannot be negative.

C. The solutions are viable because the amount of the sale is an integer.

D. The solutions are not viable because the amount charged is not a whole number.

Answer 1

B .The solutions are not viable because the amount of the sale cannot be negative.

Explanation:

In this scenario, the calculations would make sense since the online auction charges a flat fee of $1.20 plus 2% of the amount of the sale. Since the sale is said to be -5 the 2% would be -0.1 therefore, making the total charge $1.1 which is what is given in the question. Unfortunately, -5 is not a viable value for the sale because if a sale is made it means that money was paid to the seller and that would only be a positive integer not a negative one. Thus, making this solution not viable.
