An app developer projects that he will earn $230.00 for every 100 apps downloaded. Which of the following equations can be used to represent the proportional relationship between the number of apps, x, and the total earning, y.

y=2.3x

Step-by-step explanation:

Given that 100 apps downloads leads to $230.00 then we need to get earnings for 1 app download by dividing the total earnings by the number of apps

Earning per download=230.00/100=2.30

When we have x apps downs, the earnings will be equivalent to 2.3x

The total earning, y will then be

y=2.3x

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..
