Ken and paul each ordered a sandwich at a restaurant. the price of ken’s sandwich was
x dollars, and the price of paul’s sandwich was $1 more than the price of ken’s sandwich. if ken and paul split the cost of the sandwiches evenly and each paid a 20% tip, which of the following expressions represents the amount, in dollars, each of them paid? (assume there is no sales tax.)

The expression that represent the amount each of them paid is

Step-by-step explanation:

Given:

Price of Ken’s sandwich was  dollars

Paul’s sandwich was  $

1  more,

the price of Paul’s sandwich was   dollars.  

hence, the total cost of the sandwiches  dollars.  

Now The cost was split evenly,

Ken and Paul each paid = dollars

Also they have paid additional 20% as a tip.

After adding the  20

%

tip, each of them paid =

Hence the expression that represent the amount each of them paid is

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
