Answer:

w = 99 pounds

Explanation:

The problem states that Mary's weight is given by the equation:

w = 92 + g - 1

I believe the "-1" should be "-x." -1 would mean that Mary lost 1 pound. But we know that Mary lost 8 pounds, which is designated as x.

The correct equation is:

w = 92 + g - x

============

Using the correct equation, and g=15 and x=8, Mary's new weight is:

w = 92 + 15 - 8

w = 99 pounds
