Mr. Lopez wrote the equation 329+89-10g = 150 on the board. Four students explained how to solve for g.
Alyssa: "I added 32 and 8 to get 40, subtracted 10 to get 30, and then subtracted 30 from 150 to
find the value of g, which is 120."
Rahul: "I added 32, 8, and 10 to get 50, and then I subtracted 150 to find the value of g, which is -
100."
Toni: "I subtracted 18 from 32 to get 14, which I then divided into 150 to find the value of g, which is
Wilhem: "I added 32 and 8 to get 40, subtracted 10 to get 30, and then divided both sides by 30 to
find the value of g, which is 5."
Which student's work is correct?
