Answer: The budget of Alexa is increased by $100.

Explanation:

It is given that the current income of Alexa is 3 times of her previous income.

Her previous salary was $800 and current salary was $2400.

Expenses =   Rent  + Utilities  + Groceries  + Savings  + Bus

The sum of previous expenses is,

Previous expenses = $300 + $60 + $200 + $100 + $30 = $690

The sum of current expenses is,

Current expenses = $300 + $60 + $250 + $150+ $30 = $790

Effect of income on expenses is the difference of current expenses and previous expenses.

Effect of income on expenses = $790 - $690 = $100

Therefore, the budget of Alexa is increased by $100.
