Answer 2

Answer:

The income = $ 11,250

The expenses = $ 2,250

Explanation:

Given :

The ratio of the monthly income to the savings = 5 : 4

If the savings = $ 9000

To find :

The income and the expenses

Solution :

Let,

The monthly income = 5x

The monthly savings = 4x

Also,

The monthly savings = $ 9,000

So,

⇒ 4x = 9000

⇒ x = 9000 / 4

⇒ x = 2,250

★ Value of 5x :

⇒ 5 (2,250)

⇒ 11,250

The monthly income = $ 11,250

The monthly expenses :

⇒ $ 11,250 - $ 9,000

⇒ $ 2,250

Therefore,

The income = $ 11,250

The expenses = $ 2,250
