A store charges $12.50 for 5 boxes of cookies. A second store charges $8.00 for 4 boxes of cookies, but you have to buy a gallon of milk for $3.00 to get that deal.
Write the cost model equations for both stores, and find the number of boxes of
cookies that makes the costs equal.

its defiantly store b

Step-by-step explanation:

because 12.50 dollars for 5 but 8 dollars for 4 if u find out how many per box by dividing you get 2.5 on store a and 2 on store b thus sore b being a lesser cost

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
