Yuson must complete 30 hours of community service. she does 2 hours each day. which linear equation represents the hours yuson has left after x days?

Linear equation which represents the hours Yuson has left after x days is:

30-2x

Yuson must complete 30 hours of community service.

She does 2 hours each day.

i.e. in x days, hours of service done= 2x

After x days hours of service left= 30-2x

Hence, linear equation which represents the hours Yuson has left after x days is:

30-2x

We want to find a linear equation that represents the given situation.

We will get the equation: d(x) = 30h - 2h*x

Let's see how to get that, first we need to see which information we have:

We know that Yuson must complete 30 hours of community service, and she does 2 hours per day.

So she will start with 30 hours, and for each day that passes (represented with the variable x) the amount of hours reduces by 2.

We get:

d(x) = 30h - 2h*x

So for each value of x, we can get the number of hours that she has left, and the graph of this linear equation can be seen below.
