4 batches:
2/3 • 4 = 8/3
2/3 + 2/3 + 2/3 + 2/3 = 8/3
2/3 = 0.666666666666667
0.666666666666667 • 4 = 2.666666666666667
8/3 = 2.666666666666667
<span>Animals have an excretory system with a support structure called a skeleton</span>
To solve this problem you must apply the proccedure shown below:
1. First, you must multiply $8 by the hours given in the exercise:

2. Now, multiply the result obtained above by 4, to calculate her monthly income:
3. If 22% of her paycheck goes to taxes, you have:
![(800dollars)-[(800dollars)(0.22)]=624dollars](https://tex.z-dn.net/?f=%28800dollars%29-%5B%28800dollars%29%280.22%29%5D%3D624dollars)
Therefore, the answer is: $624
