Answer:
The expression that represent the amount each of them paid is [tex]1.2x+0.6 \ dollars[/tex]
Step-by-step explanation:
Given:
Price of Ken’s sandwich was [tex]x[/tex] dollars
Paul’s sandwich was $
1 more,
the price of Paul’s sandwich was [tex](x+1)[/tex] dollars.
hence, the total cost of the sandwiches [tex]= x+x+1=2x+1[/tex]dollars.
Now The cost was split evenly,
Ken and Paul each paid = [tex]\frac{2x+1}{2}=\frac{2x}{2}+\frac{1}{2}= x+0.5[/tex] dollars
Also they have paid additional 20% as a tip.
After adding the 20
%
tip, each of them paid = [tex](x+0.5)+\frac{20}{100}(x+0.5)=(x+0.5)+0.2(x+0.5)= 1.2(x+0.5)= 1.2x+0.6 \ dollars[/tex]
Hence the expression that represent the amount each of them paid is [tex]1.2x+0.6 \ dollars[/tex]
