Cory buys and sells baseball cards on ebay. He always buys at the same price
and then sells the cards for $2 more than he buys them.
One month he broke even after buying 56 cards and selling 49.
Find his buying price and selling price.
:
Let x = buying price
then
(x+2) = selling price
:
bought$ = sold$
56x = 49(x+2)
56x = 49x + 98
56x - 49x = 98
7x = 98
x = 98%2F7
x = $14, buying price, obviously then, $16 is the selling price
:
Check
56(14) = 49(16)
