Answer:
"Brand A costs approximately $0.21 per ounce, and Brand B costs approximately $0.18 per ounce."
In order to find the rounded cost per one item (in this case, per one ounce) Susan needs to divide the total price between the number of units and after that, round the result obtained up to the nearest cent.
Therefore:
Brand A
2.55$/12 ounces= 0.2125 $/ounce
As the third decimal digit, 2, is closer to 0 than to 9, then we maintain the second decimal digit as 1.
The price per unit of brand A after rounding it up is 0.21 $ per ounce
Brand B
1.45$/8 ounces= 0.1812
As the third decimal digit, 1, is closer to 0 than to 9, then we maintain the second decimal digit as 8.
The price per unit of brand B after rounding it up is 0.18 $ per ounce

Answer:
A: 244 pounds
B: 122 pounds
C: 274 pounds
Step-by-step explanation:
We have A+B+C = 640; A=2B; C=A+30. Substituting the last into the first gives ...
A + B + (A +30) = 640
2A +B = 610 . . . . . . . . . . . . subtract 30
Substituting the second into this equation gives ...
2(2B) +B = 610
B = 610/5 = 122 . . . . . divide by 5
A = 2B = 244 . . . . . . . .find A from B
C = A+30 = 274 . . . . . find C from A
Box A weighs 244 pounds; box B weighs 122 pounds; box C weighs 274 pounds.
X = half width of tent
Tan(40) = 6/x
x = 6/Tan(40) = 7.15
2x = 14.30 feet the width of the tent
