tuesday	25	29	121.15

what is the cost per click on website 1?

(5.1-5.5 notes)

Explanation:

Step1: Find the difference in clicks on Website 1

The number of clicks on Website 1 on Monday is 15, and on Tuesday is 25. The difference is \(25 - 15 = 10\) clicks.

Step2: Find the difference in total cost

The total cost on Monday is $94.15, and on Tuesday is $121.15. The difference in cost is \(121.15 - 94.15 = 27\) dollars.

Step3: Calculate cost per click on Website 1

Since the number of clicks on Website 2 is the same on both days, the difference in cost is due to the difference in clicks on Website 1. So the cost per click on Website 1 is \(\frac{27}{10} = 2.7\) dollars.

Answer:

The cost per click on Website 1 is \(\$2.7\)
