Oscar makes purchases of an existing product (X) such that the marginal utility of the last unit he consumes is 10 utils and the price is $5. He also tries a new product (Y) and the marginal utility of the last unit he consumes is 8 utils and the price is $1. The equal marginal principle suggests that Oscar should rev: 04_09_2018 Multiple Choice increase his consumption of product Y and decrease his consumption of product X.

Based on the information given we were told that the already existing product (X) has a marginal utility of 10 utils as well as the price of the amounts of $5 while the new product (Y) has a marginal utility of 8 utils as well as the price of the amounts of $1 which means that PRODUCT Y marginal utility and price is lower than that of PRODUCT X marginal utility and price.

Therefore equal marginal principle suggests that Oscar should INCREASE his consumption of product Y and DECREASE his consumption of product X reason been that product Y has a lower marginal utility of 8 utils and the price of the amounts of $1 which means that his consumption of Product Y has to be INCREASED while product X on the other has a higher marginal utility 10 utils as well as the price of the amounts of $5 which means that his Consumption of Product X has to DECREASED.
