Explanation:

Pregunta 5

Marginal product is the change in output from adding one more unit of input (here, a worker). Initial output: 8 pizzas/hour, after new worker: 12 pizzas/hour. Change is \( 12 - 8 = 4 \), which matches marginal product. Marginal cost relates to cost, marginal benefit to benefit, marginal utility to satisfaction (not output), so d is correct.

In supply analysis, a decrease in supply shifts the supply curve left (less quantity at each price), an increase shifts it right (more quantity at each price). Other options (ahead/back, up/down, right/left for increase/decrease) don't fit supply curve shifts. So a is correct.

Answer:

d. marginal product
