Answer:
monthly income can be calculated by using equation 0.025x -120.
Step-by-step explanation:
Given:
1 banner ad earns = $0.005 per click
Number of banner ads = 5
Cost to operate website = $120
Let number of clicks be x
Now 1 banner ad earns = $0.005x
5 banner ads will earn = money earned by 5 banner ads
By using Unitary method we get;
money earned by 5 banner ads = 5 × $0.005x = $0.025x
Now we need to find monthly income.
Monthly income can be calculate by Subtracting Cost to operate website by money earned by 5 banner ads.
Monthly Income = money earned by 5 banner ads - Cost to operate website = $0.025x - $120
Hence monthly income can be calculated by using equation 0.025x -120.
