Chin canned a number of quart jars and a number of pint jars of tomatoes from his garden. a pint is 16 ounces and a quart is 32 ounces. the number of pints he canned is represented by  p, and the number of quarts he canned is represented by  q. which equation models the scenario if chin canned a total of 1,280 ounces?

We have two variables p and q that need to be found.

p = # of pints

q= # of quarts

16p+32q=1280

- you do not jump into looking for the answer to each variable as it is asking for an equation not to find what p and q is

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
