Three friends go to a restaurant. They share a meal. They decide to split the cost of the meal equally. Each friend also contributes $2 for the tip. Write an algebraic expression for the amount each friend pays. Show your work.

+ 2 = f

Step-by-step explanation:

So three friends and +6 for the tip in total.

Let's say our total paid is t and how much each friend pays is f.

+ 2 = f

I said this because the total paid was split between three, and then they paid 2 dollars for the tip each too.

2 x t divided by n

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

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