Answer:
on a higher indifference curve that is tangent to the new budget line
Explanation:
When there is an increase in the income of the consumer it implies that the consumer will be consume more of both the goods.
The budget line of the consumer will shift to the right. The consumer will now consume a bundle at a higher indifference curve to increase consumption of both the goods.
The optimal bundle will be where the higher indifference curve is tangent to the new budget line.
