There are 40 tables in a library, with 30% of them seating 4 people. the tables remaining only seat 22 people. how many seats are there in the library?

30% of 40 can be calculated as 40×0.3=12. So 12 tables seat 4 people, which gives 12×4=48 seats. There are a remaining 22 seats, so do 48+22=70 seats in total

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
