Question

At the end of an advertising campaign, the weekly sales declined. The weekly sales y (in dollars) are modeled by the equation y = 6,000(4-0.09x), where x is the number of weeks after the end of the campaign.

2A) Determine the sales at the end of the campaign.

A)$6,000

B)$8,000

c)$24,000

d)$1,000

Answer 1

Answer:

c)$24,000

Step-by-step explanation:

The function that models the decline of the sales is

$y = 6000(4 - 0.09x)$

where x is the number of weeks after the end of the campaign.

At the end of the campaign, will be no more weeks left.

So we x=0, and solve for y,

$y = 6000(4 - 0.09 \times 0) \\ y = 6000(4 -0) \\ y = 6000(4) = 24000$

The correct answer is c)$24,000
