if 375 J of heat are absorbed by the system, and it has 425 cal of work done by it, compute the change in the internal energy, and interpret the sign of your result

Change of internal energy equals heat transferred to plus work done on the gas: 
∆U = Q + W 
= 375J -1778.2J 
= -1403.2J

Let me know if there is any problem
