Question

users of the new app may click on ads, which are external links. the number of times the average user clicks on an external link in a week, c(x), is modeled by the equation c(x) = -x + 10.4, where x is the number of weeks since a user purchased the app. select the correct answer from each drop - down menu. for help, see this worked example. in the sixth week after purchasing the app, the average user will click on external links about times. the average user will click on an external link two times in the week.

Explanation:

Step1: Substitute x=6 into c(x)

$c(6) = -6 + 10.4$

Step2: Calculate clicks at week 6

$c(6) = 4.4$

Step3: Set c(x)=2, solve for x

$2 = -x + 10.4$

Step4: Rearrange to find x

$x = 10.4 - 2 = 8.4$

Answer:

In the sixth week after purchasing the app, the average user will click on external links about 4.4 times.
The average user will click on an external link two times in the 8.4 week.
