The fourth wrestler weighs 143 pounds.
125+183+169+143 = 620
620/4 = 155
number b I had that as my answer and got it right
First, find 40% of 3,000:
0.40 * 3000 = 1200
So they raised 1200 so far.
Now subtract 1200 from the total they want to raise:
3000 - 1200 = 1800
So they need $1,800 more to meet their goal.
