First aircraft seats : x
second aircraft seats : y
third aircraft seats : z
<span>The first aircraft has 73 more seats than the second aircraft: x = y + 73
</span>
<span>The third aircraft has 57 fewer seats than the second aircraft: z = y - 57
</span>
<span>Their total number of seats is 427: x + y + z = 427
solve these three equations, you will get:
x = 210 seats
y = 137 seats
z = 80 seats
-------------------------
you can check your answer by:
x - y = 210 - 137 = 73 correct
and
z + 57 = 80 + 57 = 137 = y correct

Answer:
Brand A = $0.19 per pencil
Brand B = $0.18 per pencil
Better Buy = Brand B (costs less)
Step-by-step explanation:
To find unit price for each, we divide the total with the number of pencils.
So, <u>Brand A:</u>
5.29/28 = $0.19 per pencil
And, <u>Brand B:</u>
8.47/48 = $0.18 per pencil
As we can see, Brand B pencils are around 1 cent less per pencil than Brand A pencils. So, we can say Brand B are a Better Buy.
