set up an expression to determine the amount of money cara earned and then simplify it. how much did cara earn in donations per viewer?
$0.47 per viewer
$0.73 per viewer
$0.38 per viewer
$0.57 per viewer

Explanation:

Step1: Calculate the total number of viewers

The average number of viewers per live - stream is 36, and there are 8 live - streams. So the total number of viewers \(N = 36\times8=288\)

Step2: Calculate the donation per viewer

The total donation is \(D=\$135.36\). The donation per viewer \(x=\frac{135.36}{288}\)

$$x=\frac{135.36}{288}= 0.47$$

Answer:

\(\$0.47\) per viewer (the first option)
