I need an image to make sure I give you a correct answer please.
20%of £800 is 800÷5 =160
800 + 160 =960
9$ for three cans then 9/3= 3 $ per can
2200 + 21.25X = 1840 +32.50X
subtract 1840 from each side
360+ 21.25X= 32.50X
subtract 21.25x from each side
360=11.25X
x= 360/11.25 = 32 minutes pool will have the same amount
21.25*32 = 680+2200 = 2880 liters
32.5*32 = 1040 + 1840=2880 liters
it will take 32 minutes and they will have 2880 liters each
9.42 is the circumference, for future refernce its just pi times diameter :)
