Arestaurant 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

1. 8 or -82. 14 or -143. -11, -3, 0, 7, 10

Hope i can you!
