Well if you are looking for the profit margin we need how much is was when she bought it, because it doesn't say, you can't say It's a increase or a decrease, so you could say this is a investment.
But considering you put this under mathematics I assume there is more to this question you forgot to post.
Answer:
$23.52
Step-by-step explanation:
So first you would have to find how much each one would be if you were buying one individual book. For that you would do 31.36/4 to get $7.84. Then since you found that for only 1 book, you would need to multiply that by 3 to get $23.52
If you mean 4 / (11/8)
= 4 * 8/11
= 32/11
= 2 10/11
= 2.909
DE. AB, is going up BC, isn't decreasing or increasing. CD, isn't decreasing or increasing. Therefore your answer is DE.
Answer:
10^2 × 10^2
Step-by-step explanation:
Given that
Write 100 times 100 that would be multiplying to the power by 10
So based on the above information
The equation that would be developed is
10^2 × 10^2
The same would be represented as an answer
