Answer:
C
Step-by-step explanation:
Producer's surplus is the gain a producer gain by selling at market price instead of selling at the smallest price the producer was willing to sell.
Miranda was willing to tutor at $ 20 but the market price of tutoring was $ 30 therefore her producer surplus = 30 - 20 = $ 10 while for Jason the price he was willing to tutor was more than the market price and therefore he therefore has $ 0 producer surplus.
