Answer:
C) $1.50; $1.00
Step-by-step explanation:
A rational consumer would continue consumption if marginal benefit is greater or equal to marginal cost. So , Sals marginal benefit must be at least equal to her marginal cost.
Cost of one pizza = $2
Cost of two pizzas = $3.50
Marginal Cost of second pizza = $3.50 - $2 = $1.50
Cost of three pizzas = $4.50
Marginal Cost of second pizza = $4.50 - $3.50 = $1
Her marginal benefit must be at least $1.50; $1.00
