Question

a family is purchasing a home in florida that is said to be 2400 ft^2. the family later finds out that this figure includes an unfinished bonus room over the garage and a garage. the garage is 440 ft^2 and the bonus room is 240 ft^2. what is the area of the actual living space?

Answer 1

The total area is 2400 ft^2. This includes the 440 ft^2 area garage, the 240 ft^2 area bonus room, and the unknown living area. Convert this an equation about the area:

       Total area = garage area + bonus room area + unknown living area.

Now just substitute the numbers and solve.
