1. broccoli, cauliflower and carrots 2. squash, carrots and cauliflower 3. cauliflower, carrots and squash I'm not going to type all the combination. So basically you have to multiply the vegetables by the number 3. So 3 x 4 is 12. Therefore he could do it in 12 different ways. Hope this helped.
I believe you are trying to ask what is the answer to c=100w and to solve for w, with this being said the answer is w=c/100 Divide 100 to both sides to get this answer.
