Frankie will have enough money to buy the player in five (5) months,
and $3 left over after he buys it.

Month    Amount this month    Total so far
   1                        $   3                     $  3 
   2                        $   6                     $  9  
   3                        $ 12                     $ 21
   4                        $ 24                     $ 45 
   5                        $ 48                     $ 93     <===

While Frankie is enjoying the clean, pure music on his new player,
he can think about posting other, future problems like this one in
the <Mathematics> section of Brainly, instead of the <English> section.
