Your small farm encompasses 150 acres, and you are planning to grow tomatoes, lettuce, and carrots in the coming planting season. fertilizer costs per acre are: $5 for tomatoes, $4 for lettuce, and $2 for carrots. based on past experience, you estimate that each acre of tomatoes will require an average of 4 hours of labor per week, while tending to lettuce and carrots will each require an average of 2 hours per week. you estimate a profit of $2,000 for each acre of tomatoes, $1,500 for each acre of lettuce and $400 for each acre of carrots. you would like to spend at least $600 on fertilizer (your niece owns the company that manufactures it) and your farm laborers can supply up to 750 hours per week. how many acres of each crop should you plant to maximize total profits

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
