A restaurant can seat 100 people. It has booths that seat 4 people and tables that seat 6 people. So far, 5 of the booths are full. What expression matches the situation?
Okay, lets say B=booths T=tables P=people without the numbers in your equation would look like this B(P)+T(P)=100 So with everything plugged in your equation is 5(4)+T(6)=100
