x represents the number of baseball cards his brother has
so the expression represents the number of baseball cards Barry has:
(Barry has 17 more than two-thirds of the number of cards in his brother’s baseball card collection. )y = 17 + (2/3)x
median- 49

find mean add all the numbers then divide by how many numbers there in this case you divide by 7
