Which statement is true out of the value of money that you save increases over time , the value of money remains constant over t
Nataly_w [17]
None is necessarily true.

Even though you have your money in an interest-bearing savings vehicle, its value (purchasing power) may actually decrease if the interest rate is not at least as great as the inflation rate.

In periods of inflation, the value of money decreases over time. In periods of deflation, the value of money increases over time. It tends to be difficult to regulate an economy so the value of money remains constant over time.

The present value of money is greater than the future value in inflationary times. The opposite is true in deflationary times.

_____
In the US in the middle of the last century, inflation rates were consistently 2-3% per year and savings interest rates were perhaps 4-6%. Money saved actually increased in value, and the present value of money was greater than the future value. These days, inflation is perhaps a little lower, but savings interest rates are a lot lower, so savings does not outpace inflation the way it did. The truth or falsity of all these statements depends on where and when you're talking about.

A decimal is considered as
dalvyx [7]
<h3>Answer:  B) real number</h3>

Explanation:

Something like 3.5 = 7/2 is a rational number because its a fraction of two integers.

While on the other hand, the constant pi = 3.14159... is irrational because we cannot write pi as a fraction of two integers. We can get approximations like 22/7, but not a perfect exact match.

Both types of numbers, rational and irrational, are under the umbrella of the real number system. Any real number is a string of decimal digits. Sometimes it might be a whole number, but fractional values can be included as well. The decimal number may terminate, or it may repeat, or it may go on forever without a pattern.

In short, any number you can think of is a real number assuming your teacher hasn't covered complex numbers (or imaginary numbers) just yet.

At a clothing store, jackets are on sale for 30% off. Sales tax is 5%. Which expression will calculate the total cost of a jacke
VLD [36.1K]

Answer: B.x(0.75)

Step-by-step explanation:

If the jacket has a cost of x, but has 30\% off and we have to add the 5\% in tax, we can write all in the following expression:

x-30\% x+5\%x

Where:

x is the cost

30\% x=\frac{30}{100}x=0.3 x is the percent off

5\%x=\frac{5}{100}x=0.05x is the tax

Then:

x-0.3 x+0.05 x=0.75 x

This can be also rewritten as:

x(0.75)

Hence, the correct option is B.
