Brandon buys a radio for 43.99 in a state where the sales tax is 7%

Answers

So then this is a simple multiplication problem. First, we need to make the percentage a decimal. To do that, we find out how many parts out of 100 it is. In this case it 7 parts, so we're making it the decimal .07. So the problem becomes 43.99x0.07. We multiply that, and come up with 3.0793. We'll round that to the hundredths place, and come up with 3.08. So on a radio that costs $43.99, you will pay $3.08 tax, bringing the total to $47.07.
43.99
Convert to a decimal. x .07
¯¯¯¯¯¯¯¯
3.0793
Add + 43.99
¯¯¯¯¯¯¯¯¯
47.0693
Round out. $47.07 is your answer

Dimtry bought a pair of pants at the discounted price of $30. The original price of the pants was $40. What was the percent of the discount? PLEASE EXPLAIN TO ME HOW YOU GOT YOUR ANSWER

Answers

Answer:

25%

Step-by-step explanation:

Say we start from the beginning with $40. If the pants are discounted but we don't know the percent discount, then we need a variable, x:

40 - x% * 40 = 30

The total is 40. When we take a discount off of 40, we are taking a percent of 40 and subtracting that from 40. From the problem, this should be 30. Thus, the equation above.

Add x%*40 to both sides and subtract 30 from both sides:

x%*40 = 10

Divide by 40:

x% = 1/4 = 0.25

Multiply each side by 100:

x = 25

The answer is 25%.

What does this mean?

Answers

Answer:

f(x) = |x| represents the modulus function or absolute value function. It gives us the distance between any point and the origin. Since distance can never be negative so we always consider its positive value only. You can simply multiply the given value with ‘-1’(if the given value is negative).
