Create a story problem for the problem 388+235

My friend James and his fiance, Mary are planning a wedding. After months of planning and cutting down on people on their guest list, they have finalized all the invites. Mary has 388 people that she wants to invite and James has 235 people he wants to invite. How many people do they want to invite all together?

Sammy and his friends decided to bake a lot of cookies to sell at the bake sale, then to provide juice boxes for a party. Sammy and his friends then baked 388 cookies and bought 235 juice boxes. How much stuff did he have in total?

Step-by-step explanation:

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
