A) Convert the percentage to decimals.

40%= 0.40

Divide, 0.40/15.0

= 21.00

$21.00 dollars is the price of the book.

B) For this, we start off with finding the discounted price.

38*.25 (converted percentage)

plus 6% of the discounted price.

The book costs $28.56

For your third question:

Convert 90% to a decimal

= 0.9/40 = 36

He answered 36 questions correctly.

In science class, the average score on a lab report is 82 points, with all students scoring within 3.2 points of the average. If
nirvana33 [79]

An equation that represents the minimum and maximum scores is; |x - 82| = 3.2.

<h3>How to write an absolute value equation?</h3>

The absolute value function is defined by:

f(x) = x, x ≥ 0.

f(x) = x, x < 0.

It measures the distance of a point x to the origin.

For this problem, the distance between the minimum and the maximum scores and the mean is of 3.2, that is, the difference between these scores x and the mean of 82 is of 3.2, hence the absolute value equation that represents this situation is given by:

|x - 82| = 3.2.
