Each month, Kaisorn deposits $50.00 onto her public transportation card. It costs her $2.50 per trip to ride the subway. Thom deposits $40.00 on his public transportation card. It costs him $2.00 per trip to ride the subway.

If x represents the number of trips and y represents the amount remaining in each account, which system of equations represents their transportation costs?

A 50 - 2.5x = y

40 - 2x = y

B 50 + 2.5x = y

40 + 2x = y

C 50 - 2.5y = x

40 - 2y = x

D50 + 2.5y = x

40 + 2y = x
