Sophie had a 15% off coupon for the book store. The original price of
the book she bought was $14.99. Calculate the discount. What was the sale price?

Answers

｡ₓ ू ₒ ु ˚ Your answer would be 12.75! ˚ ू ₒ ु ₓ｡

⭒❃.✮:▹ Considering 15% of 14.99 is 2.24, we would need to subtract that amount from 14.99.

The selling price of the book will be equal to $12.74.

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Sophie had a 15% off coupon for the book store. The original price of the book she bought was $14.99.

The selling price will be calculated as,

Selling price = 14.99 x ( 100 - 15)%

Selling price = 14.99 x ( 85 / 100 )

Selling price = 14.99 x 0.85

Selling price = $12.74

Examine the following expression.

p squared minus 3 + 3 p minus 8 + p + p cubed

Which statements about the expression are true? Check all that apply.
The constants, –3 and –8, are like terms.
The terms 3 p and p are like terms.
The terms in the expression are p squared, negative 3, 3 p, negative 8, p, p cubed.
The terms p squared, 3 p, p, and p cubed have variables, so they are like terms.
The expression contains six terms.
The terms p squared and p cubed are like terms.
Like terms have the same variables raised to the same powers.
The expression contains seven terms

Answers

Answer:

Step-by-step explanation:

Given the expression: p² -3 +3p -8 +p +p³

The following statements are true:

The constants, –3 and –8, are like terms.

The terms 3 p and p are like terms.

The terms in the expression are p squared, negative 3, 3 p, negative 8, p, p cubed.

The expression contains six terms.

Like terms have the same variables raised to the same powers.

_____

Terms are generally separated by + or - signs. (The sign is considered to be part of the term.) In the context of a polynomial, terms may be constants, or may be a product with factors that are constants or variables.

_____

Further comments on "term"

In other contexts, the word "term" is used for various purposes. It can designate a member of a sequence, the left or right side of an equation, the numerator or denominator of a rational expression, or just about any identifiable expression that can be considered as a unit. Whereas "coefficient" or "factor" may apply to just about any subset of the (prime) factors of a product, the word "term" is generally restricted to consideration of the product as a whole.
