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
C = 3
You isolate the variable by dividing each side by factors that don’t contain the variable
Answer:
Suppose the number is 4
Square of this number (4 x 4 ) = 16
Divided by 2 = 16/2 = 8
Added to 16 = 8+16 = 24
Step-by-step explanation:
Basically, the question is asking, what will happen if we increase 9 by 30%?
first, what is 30% of 9?

So, the increase will be by 2.7 days,
So the total amount will be 9+2.7=11.7 - this is the correct answer.
Answer:
2
Step-by-step explanation:
15+10=5(3+_)
25=5(3+_)
25 divide by 5 equals 5
5-3=2!
