Under his cell phone plan, Owen pays a flat cost of $46 per month and $3 per gigabyte, or part of a gigabyte. (For example, if he used 2.3 gigabytes, he would have to pay for 3 whole gigabytes.) He wants to keep his bill under $60 per month. What is the maximum whole number of gigabytes of data he can use while staying within his budget?
60 - 46 = 14 dollars to buy data
14/3 = 3 2/3 since he can only buy whole gigabytes, he can only buy ~ 3 Gb data
