The table below show the marginal utility, measured in utils, that Ricardo would get by purchasing various amounts of products A, B, C, and D. Column 5 shows the marginal utility Ricardo gets from saving. Assume that the prices of A, B, C, and Dare, respectively, $18, $6, $4, and $24 and that Ricardo has a budget of $106.
