Rick and Clara each collect baseball cards. Rick collects 3 cards per day, and Clara collects 2 cards pe day. The two started with a combined total of 40 cards.
Which equation(s) model(s) the situation if d is the number of days, and t is the total number of cards
between Rick and Clara?
Select ALL that apply.
A
50+ 40 = 1
B
40+ (3 x d) + (2 x d) =
С
(5 xd) + (40 x d) =
D
t = 40 - 30 - 20
E
(20) + (3d) + 40 =
F F
40 =23
