On a graph where the budget line is drawn with x on the horizontal axis and y on the vertical axis, the new budget line: (a) is atter than the old one and lies below it. (b) is atter than the old one and lies above it. (c) crosses the old budget line. (d) is steeper than the old one and lies below it. (e) is steeper than the old one and lies above it.

Spaghetti costs 8 units of the local currency per plate and she had 82 units of currency in her purse. If s denotes the number of plates of spaghetti and o denotes the number of oysters purchased, the set of commodity bundles that she could just aord with the money in her purse is described by the equation: (a) 82 + 6o = 82. (b) 6s + 8o = 82. (c) 8s + 7o = 82. (d) 5s + 6o = 82. (e) There is not enough information to determine the answer
