How do you do markdowns and markups

Mathematics

So the book guy mark downed the price of the books by 46%, also known as 0.46.  All decimals are less than 1.  So then, what you do is you take b, which is the variable defining the price of the book, then you multiply it by 0.46.  So the answer of b would be b x 0.46.  For C, you must do 29 x 0.54, and that will give you the answer for C.  Finally, in D, take the answer you got in C, and subtract that by 29.  This will give you your answer.

A small cargo plane currently has 140 pounds of cargo aboard. In addition, n boxes weighing 45 pounds each will be brought aboar
Vika [28.1K]

Answer:

The inequality that represents this situation is: 140 + 45*n < p

Step-by-step explanation:

Since the plane already had 140 pounds on board and "n" boxes will be loaded on it, then the weigh of each box multiplied by the number of box should be the extra cargo on the plane. This extra cargo added to the previous load must be less than the limit of cargo the plane can take as shown below:

140 + 45*n < p

Eddi Din [679]

Answer: Choice C

0 \le d \le 2

Graph with filled in circles at d = 0 and d = 2, shading in between

==========================================

Explanation:

d = amount downloaded in gigabytes

The smallest amount is d = 0. We cannot download a negative amount of data, so this is why d = 0 is the smallest.

The largest amount allowed is d = 2. This is the cap that the ISP has set up.

So basically d can be anything between d = 0 and d = 2, including both endpoints. This means 0 \le d \le 2

We use filled in circles for both endpoints to show to the reader "include these endpoints". Shading is done in between to show the entire solution set of possible d values. For instance d = 1 is in that region so it is possible to have this solution. Something like d = 4 is outside the region and not possible.
