I believe both of these hands have clear cut decisions .

First , I will assume you're a profitable player so you expect to earn some positive amount per hand .

Your equity for q-7 is about 51.8% . Your $/hand if you make the call is (2*(buy-in -rake)*.518 - buyin )/hand < 0 . Clearly your $/hand is a negative number so you would elect to fold . On the other hand , as Lordmushroom pointed out , if you're a lousy player then you would be glad to call in this spot since you minimize your losses .

2) With q-8 , your equity is around 53.5 % which means your $/hand is (2*(buyin -rake)*0.535 - buyin)/hand =(buyin-rake)*0.02/hand

So if your buy in is 105 , then you profit $2 for every hand . If you fold , you must believe that your worth is more than $2/hand . Therefore even if you expect to win 67% of the time and your average duration is about 30 hands , then your $/h is $29/(30 hand) which means you're making a mistake if you fold q-8 .

This is more closer to the truth if it is given that we have a game waiting for us once the match ends .
