whew...this one had me stumped for a bit. My mistake was assuming the 1 hour all took place in one call. But to save the maximum amount he would have to make 60 calls, each one minute in duration. Granted, this would also be the plan that would spend the most money, but it's also the one that would save the most too.
Since 40% of $1.60 is $0.64, he would save $38.40 (.64 x 60). But then you must subtract the $25 monthly charge which reduces the total savings to a grand total of $13.40.
The correct answer is C, $13.40 (I hope....lol)
