2004

Step-by-step explanation:

Given :

Sales at a certain department store follow the model where y is the total sales in thousands of dollars and x is the number of years after 2001.

To Find: What was the first year that sales fell below $50,000?

Solution:

We are supposed to find the first year that sales fell below $50,000

Since y = total sales in thousands of dollars

So, Substitute y = 50

x≈ 3

The first year that sales fell below 50,000= 2001+3

                                                                     = 2004

Hence the first year that sales fell below $50,000 was 2004.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
