Unsure why C is correct..

Roger and Shelly can both contribute 30\$ each and Terry donates \$290 or they can contribute \$20 each and terry contributes \$310 which still satisfies statement A and the prompt that terry continued more than the other two combined.

I picked E

I also picked E for the same reason. Are we sure OA is correct?

I have also picked E.

Roger and Shelly can pick any number from 1 to 75 and satisfy (1) and (2).

Let R+S = x...be their contribution combined

Given T = 50 + x

Stat 1: T+R+S = x+50+x = 350 => x =150.

R+S = 150...but we can' exactly say the S value...Insufficient..

Stat 2: R = S..

Then 2S = x..from question stem....we don't know the x value..

Both : x +50 +x = 350 => x = 150.

2S = 150 => S = 75.
