Final answer:
Raji's new monthly expense for sharing a house with Jon, including his share of rent and utilities, would be $600, a decrease from his current expense of $675 for his one-bedroom apartment.
Step-by-step explanation:
The question asks us to calculate Raji's new monthly expense if he decides to rent a house with his friend Jon, where the total monthly rent is $900 and utilities are $300. If they split these costs evenly, we can calculate Raji's monthly expense by adding half of the rent to half of the utilities cost. First, we split the rent: $900 divided by 2 equals $450. Then, we split the utilities: $300 divided by 2 equals $150. Adding these together, $450 plus $150 equals $600.
Raji's New Monthly Expense:
Raji's new monthly expense will be $600, which is the sum of half the rent and half the utilities. Therefore, the correct answer is B. $600 even though it was not listed in the original options provided. This represents a decrease from his current expense of $675 for renting a one-bedroom apartment.
