Question

A Web developer uses the equation y=110x+20, where x is the number of cents spent on advertising, to estimate the number of visitors a website receives in 1 day.

How many visitors should the Web developer expect in a week (7 days) if he spends 5 dollars a day on ads?

Answer 1

Answer:

385,140

Step-by-step explanation:

The number for one day is predicted to be 110·500+20 = 55020, so the number for 7 days is expected to be 7 times that value.

7·55020 = 385,140
