If you put your 3 biggest rooms in the 3 rooms for $270" deal and then pay $0.60/ sq. ft. for the rest , how much will you pay?

Answer 1

$396

Explanation:

First, determine the area of all the rooms:

• Area of Bedroom 1 = 9x10 = 90 sq.ft.

,

• Area of Bedroom 2 = 10x12 = 120 sq.ft.

,

• Area of Bedroom 3 = 11 x 16 = 176 sq.ft.

,

• Area of the living room = 14x16 = 224 sq.ft.

,

• Area of the dining room = 14x14 = 196 sq.ft.

Thus, the three biggest rooms are bedroom 3, living room and the dining room.

• The total area of the other two rooms = 90+120 = 210 sq.ft.

Since the cost for the rest is $0.60/ sq. ft.:

`\begin{gathered} \text{Total Cost}=270+0.60(210) \\ =270+126 \\ =\$396 \end{gathered}`

You will pay a total of $396.
