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 negative 100 ” Toni: “I subtracted 18 from 32 to get 14 , which I then divided into 150 to find the value of g , which is 10 and 5 sevenths ” 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?
