Please evaluate the correct solution of the following Problem
Problem- So your nutritionist recommends that your diet include at least 140 milligrams of Vitamin A and at least 145 milligrams of Vitamin B each day. You can get these two vitamins from two main food types One and Two. Type One contains 10mg of Vitamin A and 20mg of Vitamin B per pound. Type Two contains 30mg of Vitamin A and 15mg of Vitamin B per pound. Type one costs $12/lb and Type Two costs $8/lb.
Part 1- How much of Type One should be purchased? and how much of Type Two? (two decimal places)
I need assistance to compute the quantity of food type one.
