Robin consumes two goods X and Y. Each additional unit of X yields Robin the same happiness as each additional unit of Y. But each unit of X costs $5 while each unit of Y costs $2. Robin wishes to spend $20. Which of the following statements is CORRECT? 1. Robins indifference curves are straight lines that are flatter than the budget constraint. In maximizing utility, Robin will consume 10 units of Y and zero units of X. 2. Robins indifference curves are straight lines that are steeper than the budget constraint. In maximizing utility, Robin will consume 10 units of Y and zero units of X. 3. Robins indifference curves are straight lines that are flatter than the budget constraint. In maximizing utility, Robin will consume 4 units of X and zero units of Y. 4. Robins indifference curves are straight lines that are steeper than the budget constraint. In maximizing utility, Robin will consume 4 units of X and zero units of Y..
