Answer:
w = 99 pounds
Step-by-step 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
