A. $2.70

Step-by-step explanation:  

We are told that Eryn and seven of her friends go out to lunch. The total bill comes to $143.35. They decide to leave a 15% tip. Each person will contribute an equal amount to the total tip.

First of all we will find the amount of tip by finding 15% of $143.35.

Now let us find amount that each person will contribute by dividing 21.5025 by 8 as Eryn and her seven friends will contribute an equal amount to the total tip.    

Therefore, each person will contribute $2.70 to the total tip and option A is the correct choice.

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
