There are 2800 homes in the town of plaquemine. each home uses an average of 380 gallons of water each day. what is the total number of gallons used in plaquemine per week?

(2800*380)*7= 7448000

You would multiply 2800 by 380 as you want to find the amount of water used per day. Multiply this by 7 as there are seven days a week. You should get 7,448,000 gallons per week. 

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%
