  THE CONTAINER HAS TO DISPLACE SUFFICENT  VOLUME OF WATER TO COUNTERACT THIS WEIGHT

1CU FT = APPROX 6.5 GALLONS = 65LBS   THEREFORE YOUR CONTAINER  NEEDS A MIN OF ONE CU FT PER 65LBS OF WEIGHT

HOPE THIS HELPS

HI  I WILL HELP YOU WORK THIS PROBLEM OUT

YOU FIRSTLY WORK OUT THE CUBIC  FT LOST PER NIGHT  THEN MULTIPLY THIS BY DAYS IN MONTH

SO SURFACE AREA OF POOL IS   30ft X 22ft = 660 sq ft  THE DEPTH LOST IS 1inch PER NIGHT THEREFORE  660 X 1/12  = 55cu ft 

THERE IS 6.42851 UK GALLONS IN 1 CU FT  OR 7.485051 US GALLONS IN CU FT

THEREFORE  IN UK  55 X 6.42851 =  353.568 GALLONS LOST PER NIGHT

I WILL LEAVE YOU THE REST TO WORK OUT BY SUBSTITUTING  THE US GALLONS  THEN MULTIPLYING THE NUMBER OF DAYS N THE MONTH  OR YEAR

HOPE THIS HAS HELPED YOU

HI  4( 5n-7) = 10n + 2       =     20n-28 = 10n + 2      =  20n  =10n + 30    =20n - 10n = 30

therefore         10n = 30      therefore    n = 3  

REMEMBER WHEN YOU TAKE NUMBERS FROM ONE SIDE OF THE EQUAL SIGN THEY CHANGE   IE:    + BECOMES -   AND X  BECOMES DIVIDE  AND VISA VERSA
