The theater has 9 chairs in a row and there are 4 rows there are 36 chairs and for an upcoming show, the theater needs to have 4
times as many chairs, they are able 3 more chairs to each row and they can add as many rows as you want and how many rows do they need if they need 144 chairs
so you basically want to add the numbers first but not 144 you want to see if those numbers add up to 144 or if its not enough, then you will need to subract 46 and 144 for get your answer! Btw if this is wrong im sorry but i hope it helps you.
