Agrocery store sells a six pack of bottled water for $3.79, a nine pack for $4.50 and a 12 pack for $6.89 which package costs the least per bottle? explain your reasoning.

So to find out how much each bottle costs you have to multiply the cost with the number of bottles.

$3.79 / 6 = $0.63

$4.50 / 9 = $0.5

$6.89 / 12 = $0.57

So the package that cost least per bottle would be the 9 pack for $4.50 because each of the bottles cost $0.5.

Hope this Helps!!

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
