Question

You develop an app to help students complete their homework. To earn money, you sell advertising space on the app’s main screen. An advertiser pays you $30 per month and an additional $0.002 each time the app is opened. Graph the linear equation that represents the monthly income y (in dollars) when the app is opened x times.

Answer 1

Linear equation is
`y=0.002x+30`

Explanation:

We have,

Total monthly income (in dollars) = y

Number of times an app is opened = x

As, the advertiser pays $0.002 each time an app is opened.

So, the amount paid by the advertiser if an app is opened x times = 0.002x dollars.

Since, $30 per month is also paid by the advertiser.

Thus, total monthly income 'y' is given by,

`y=0.002x+30`

Hence, the graph of the linear equation is given below.
