The owners need to advertise the business online. there are two companies that have sent you the proposal for web posting in creating a website. the cost for web posting offered by two companies are shown. find the number of months after which the total cost of web hosting is the same for both companies.

Let x = number of months.

a)
People's choice: cost = 10 + 21.93x

Top Co.: cost = 0 + 22.45x, or simply
cost = 22.45x

b) To see for what value of x, the month, the costs are equal, set the cost equations equal and solve for x.

10 + 21.93x = 22.45x

Subtract 10 from both sides.

21.93x = 22.45x - 10

Subtract 22.45x from both sides.

-0.52x = -10

Divide both sides by -0.52.

x = 19.23

In 19.23 months the costs are the same.

c) Plot the two equations:
y = 21.93x + 10
y = 22.45x

A= r2 × 3.14 11×11 ↓ ↓ 121 × 3.14 = 379.94 → 379.9

Hope this ; )
