Explanation / Answer

No.of cans used per week by one person = 4 No.of cans used per year by one person = 4 * 52  Since No.of weeks in 1 year = 52                                                              = 208 No.of cans used per year by 280 millon people = 208 * 280* 10^ 6     Since 1 millon = 10 ^ 6                                                                         =58240* 10 ^ 6                                                                        = 58240000000 can / yr (2) we know 1 ton equals 32000oz given weight of each can = 0.5 oz So, weight of 58240* 10 ^ 6 cans = 58240* 10 ^ 6 * 0.5 oz                                                     = 29120 * 10 ^ 6 oz                                                      =( 29120* 10 ^ 6 ) / 32000 ton                                                     = 0.91 * 10 ^ 6 ton                                                     = 910000 ton
