Answer:
part A : $4
part B : $16
Sue buys a certain brand of cereal that costs = $12 per box.
She changes to a super-saving brand of the same size.
The equation showing price y as a function of the number of boxes, x is for the new brand.
y = 8x
for x = 1, y = 8
So for 1 box super-saver cereal brand costs $8.00
Part A. - So saving per box = 12 - 8 = $4
Part B. - Money saved in 1 box = $4
Therefore, money saved in 4 boxes = 4 × 4 = $16

Answer:
5 < x < 21
Step-by-step explanation:
The sum of the shorter sides is greater than the longest side.
If 13 is the longest side:
x + 8 > 13
x > 5
If x is the longest side:
8 + 13 > x
21 > x
Therefore, the third side is any number between 5 and 21.
I’m not sure if this is right. But I think it’s 29
x=4
8(4) -3
32-3=29
I hope this helps you
