Between 1998 and 2018, inflation for prices of goods and services has been about 51%. Suppose a salon charged $18 for a basic ha
ircut in 1998 and has been raising prices by a steady percentage each year to keep up with inflation.
1 answer:
Answer: $22.12
Step-by-step explanation:
I just did the compound interest formula which is
starting amount * (1. interst rate) ^ number of years
example if you have 100$ and you want to know how much it is worth if it appretiates by 7% of a period of 20 years it would look something like this;
100 * (1.10) ^20 = 672.74$
but since you have to figure out what it was in 2008 which was exactly half way in the period you divide the exponent by half so your formula should be;
I know the answer is right because I asked my teacher and it's correct.
REAL EXAMPLE: 18 * (1.51) ^.5 = 22.12$

The most direct form to graph a line, is to find two points of it and connect them with a line.
Here we have:
Let's find the point where x = 0. To do this, we replace the x in the equation by 0:
We have our first point: (0, -6)
Next let's find the point where y = 0. Again, we replace y in by 0 in the equation:
We have our second point, (3, 0)
Now all we have to do is plot the points (0, -6) and (3, 0) in the plane, and connect them with a line, and then the line is graphed
The line should look like this:
