How many bottles of sparkling water does Mary Anne drink in a year? ** She drinks 1/5 of a bottle of sparkling water every night so over an entire year she drinks .2*365 = <<1/5*365=73>>73 bottles of sparkling water
How much does Mary Anne spend on sparkling water every year? ** Every bottle costs $2.00 and she drinks 73 bottles a year so she spends 2*73 = $<<2*73=146.00>>146.00 a year on sparkling water
