Luis and his best friend Faith want to spend as much time as possible at the local amusement park this summer, so they’re going
to buy season passes. The passes are normally $120 each, but for three days only, they’re on sale: Buy one, get one half off. Luis agrees to wait in line to buy them the season passes, and they’ll split the cost evenly. How much will Faith owe Luis?
First, we have to find how much it costs in total. 120+60(the pass half off)=180. Since they decide to split the cost evenly, they will divide the cost by 2 180/2=90. Faith will owe Luis $90.
