The mulraney's home has 2,550 square feet of living space. a contractor is building an addition to their home that will increase the square footage by 8%. what will be the square footage of their home with the addition?

First we have to find out how much the Mulraney's square footage increases with the addition.  To do this, we should multiply the percent of expansion, 8% (0.08) by their current square footage (2, 550)

0.08 * 2,550 = 204

This means that the addition is adding 204 square feet to the Mulraney's house.

To find the total number of square footage, we just add the original (2,550 feet) to the addition (204).

2,550 + 204 = 2754

Therefore, the square footage of the Mulraney's home with the addition is 2754 square feet.
