Final answer:
When the price of good y decreases from $18 to $14, the budget constraint will shift outward or to the right. This means that the consumer will be able to afford more of both goods x and y.
Step-by-step explanation:
When the price of good y decreases from $18 to $14, the budget constraint will shift outward or to the right. This means that the consumer will be able to afford more of both goods x and y. The new budget constraint will be tangent to a higher indifference curve, indicating an increased level of utility.
