Cherise considers movies and concerts to be perfect substitutes. When Cherise maximizes her utility, what will her optimal bundle of movies and concerts probably look like? Cherise’s indifference curves will be straight lines. Her optimal bundle will likely consist of just 1 good. Cherise’s indifference curves will be convex to the origin. Her optimal bundle will likely include both goods, with the relative proportions partially determined by their relative prices. Cherise’s indifference curves will be L-shaped. Her optimal bundle will include both goods, consumed in a fixed proportion. Cherise’s indifference curves will be concave to the origin. Her optimal bundle will likely consist of just 1 good.

Cherise’s indifference curves will be straight lines. Her optimal bundle will likely consist of just 1 good.

Explanation:

When two goods are perfect substitutes, their indifference curve is a straight line. The slope of the line is negative and it is -1, since any increase in the price of good A will result in the purchase of good B.

Indifference curves that are L-shaped result from two goods being perfect complements, not perfect substitutes.

Generally, indifference curves are convex, since the more you consume of good A will result in a higher substitution rate for good B.

Concave indifference curves are not common, since the more you consume of good A results in a lower substitution rate of good B, i.e. the more you consume of good A results in you wanting less of good B.

can your question and add a list so i can you out?
