2 answers:
Answer:
Discounted price= 0.7 p
Step-by-step explanation:
Original price = p
Since we are given that 30 % is off on the price
So, 30 % of p
So, the discount is of amount 0.3p
So, the discounted price = Original price - Discount amount
So,the discounted price = p-0.3p
Discounted price= 0.7 p
Hence expression can be used to find the price of the shoes after the discount is 0.7p

<h3>Answer: Choice C) Real, Rational</h3>
=============================================
Explanation:
Any number you'll encounter so far in your math course will be a real number. This is until you get to something like which is a complex number, but your teacher may not have covered that chapter yet.
Anyways, -5 is a real number because we aren't taking the square root of a negative or anything like that.
-5 is also an integer, but that choice isn't listed. The set of integers is any positive or negative whole numbers, including 0 as well.
Furthermore, -5 is considered rational because -5 = -5/1. We can write -5 as a fraction of two integers where 0 is not in the denominator. With -5 being rational, it cannot be irrational. The term "irrational" means "not rational".
