Help and i will give brainiest if you answer them all if random will report

First one: A

Second one: 15%
To find the percent markdown you would need to find the difference between the beginning price and the decreased price, then find the percentage by dividing the difference by the beginning price.

Third one: -13w - 7

Last one: A rational number is a number that can be expressed as the quotient or fraction of two integers. Every integer is a rational number.
Hope this helped!

I think 1- is A and than 2- I think it’s 13 percent

What is the inequality?

It’s either a or c as the answer.
