The Phony Bologna Meat Company offers two platters. Platter A comes with 4 hamburgers, 3 hot dogs, and 2 pig's feet, and costs $15. Platter B comes with 3 hamburgers, 4 hot dogs, and 5 pig's feet, and costs $12.
A picnic organizer requires 220 hamburgers, 270 hot dogs, and 250 pig's feet. (There can be leftovers, but these are the minimum requirements.) What is the minimum cost (in dollars)?

Teri finds a pile of money with at least $600. If she puts $200 of the pile in her left pocket, gives away 4/5 of the rest of the pile, and then puts the rest in her right pocket, she'll have more money than if she instead gave away $600 of the original pile and kept the rest. What are the possible values of the number of dollars in the original pile of money? (Give your answer as an interval.)
Please give me the answer!

Compare:
Give your answer as a five letter word, all capital letters and no spaces. For example, if you think that E < B < C< D< A, then you would answer EBCDA.

Anyways, i have a new problem:
1)Let line
be the graph of . Line is perpendicular to line and passes through the point (10,10). If line is the graph of the equation y =mx + b, then find m+b.2) Find B-A if the graph of Ax + By = 7 passes through (2,1) and is parallel to the graph of 2x - 7y = 3
3)The "perpendicular bisector" of the line segment
is the line that passes through the midpoint of and is perpendicular to .The equation of the perpendicular bisector of the line segment joining the points (1,2) and (-5,12) is y=mx+b. Find m + b.

I have a large truck and my neighbor has four identical small trucks. My truck can carry at least 800 pounds more than each of her trucks, but no more than one-third what all four of her trucks combined can carry. Knowing only these facts, what is the largest number of pounds that I can be assured of being able to carry in my truck?
