Explanation:
The utility-maximizing model is a model theory of a consumer which shows how consumers try to allocate their income money. It is believe that every customer is a rational being and try to get the optimized value for their money spent. Consumers' resources are limited so that their incomes are also limited. Consumers have budget constraint.
According to the Utility Maximization theory, every consumers try to decide to spend their incomes so that the last pie spent on a product yields an amount which is equal to the extra marginal utility.
Thus a utility-maximizing consumer, Jane who is spending his income on wallets and eyeglasses will increase the purchased of wallets, when the price of the wall decreases, if the wallets are considered a normal good and the income effect of Jane will reinforces the substitution effect.
Therefore the answer is ---
increase; normal; reinforces
