Good x sold for $40 in 1945. the Cpi in 1945 was 18.0 and the cpi in 1999 was 166.6. what was the price of good x in 1999 dollar
andrey2020 [161]

Answer:

the price of good x in 1999 dollars is 370.89 dollars

Step-by-step explanation:

Given that good x sold for $40 in 1945. the Cpi in 1945 was 18.0 and the cpi in 1999 was 166.6.

We have cpi and sale price have direct variation

In other words S = kC where C = CPi and S = sales price

In 1945, 40 = 18k or K = 20/9

Using this we can say

Sales price in 1999 would be k (166.6)

=\frac{20}{9} (166.6)\\= 370.89

the price of good x in 1999 dollars is 370.89 dollars

The x- and y- coordinates of point N are both negative. In which quadrant is point N located?
meriva

Answer:

<em>N </em>is located in the third quadrant

Step-by-step explanation:

since the y coordinate is a negative and so is the x coordinate, the negative y would push <em>N </em>down and the negative x would push it left, landing the coordinates of <em>N</em> in the 3rd quadrant.
