Costa earned a gross commission of 2101.05 during july. what were his sales if his rate of commission is 10.5% of net sales and sales returns and allowances for the month were 8% of his gross sales?

  $21,750

Step-by-step explanation:

If returns and allowances were 8% of Costa's sales, then his net sales were 92% of his gross sales. His commission is figured on net sales, so we have ...

  commission = rate × net sales = rate × (92% × gross sales)

  $2101.05 = 0.105 × 0.92 × gross sales

  gross sales = $2101.05/(0.105×0.92) = $21,750

Costa's gross sales for July were $21,750.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

a.)the line for function b is steeper
