marginal benefit - ANS-the benefit of the next unit
(if marginal benefit > marginal cost, it's a good choice)
Opportunity cost - ANS-includes the cost you directly pay PLUS the value of the
alternative activity you give up. includes all cost, both implicit & explicit. also is the best

outwards
what happens to the PPF if a technological change that affects only one good occurs? -
ANS-the PPF will rotate and therefore change it's slope
