Jeremy has a loan from the bank. He owes $128,271.60 including interest. He plans to pay the loan back in 18 years. How much must Elijah pay each month to have the loan paid in 18 years?

4 : 3 : 2

x - area unit

area of the kitchen = 4x

area of the playroom = 3x

area of the dinning room = 2x

The combined area of these three rooms is 189 ft².

Therefore we have the equation

4x + 3x + 2x = 189

9x = 189    |:9

x = 21 ft²

area of the kitchen = 4x = 4(21) = 84 ft²

area of the playroom = 3x = 3(21) = 63 ft²

area of the dinning room = 2x = 2(21) = 42 ft²
