You take your cost of the chips (Lets say it is 2.50 a bag so $5 for two bags).
20% off means it will be at 80% of the full price so you multiply
5 x 0.8 = 4
Now if you add in the discount of your $1 coupon, you have 4 - 1 = 3 so your final answer would be $3.
(Keep in mind, I was given no cost for the chips so I made one up. This is just to explain the procedure.)
Answer:
True
Step-by-step explanation:
7y and 8y are like terms, so you can add them together
Answer:
the MEAN for class a is 72.6
the MEAN for class b is 84.0
if you take these means and compare them, you can see that on average, class B performed better.
the MEDIAN for class a is 72
the MEDIAN for class b is 85
Step-by-step explanation:
Perimeter (p) = 2×length (l) + 2×width (w)
p = 2l+2w
area (a) = l×w, so solve for one (I'll use l):

since p = 30, and a = 50, substitute the "a÷w" in for l in the perimeter equation:

Now plug in p and a values:


therefore width can be either 5 or 10 (but not both), so let's plug in:
l = a÷w = 50÷5 = 10
So if w = 5, then l = 10
D) 5 feet, and 10 feet
