Altogether is 400 because total means to add and 200 + 200 = 400. That's the answer to your question.
there are 16 ounces in a pound so 16x7=112 +2= 114
12 I’m pretty sure because you have x then 3 then 12
72.22 I think I’m sorry if I’m wrong
200/5 = 40...she should read at least 40 per day to reach her goal
