Jerimiah and Darren both collect baseball cards. Jerimiah starts with 11 cards and collects 3 cards each week. Darren starts with 5 cards and collects 4 each week. Which system of equations can be used to determine the number of weeks it will take for Jerimiah and Darren to collect the same number of cards?
a. y = 3x + 11 and y = 4x + 5
b. y = 11x + 3 and y = 5x + 4
c. y = 3x + 5 and y = 4x + 11
d. y = 3x + 4x and y = 11 + 5
