Suppose a basket of goods and services has been selected to calculate the CPI and 2012 has been selected as the base year. In 2012, the basket's cost was $77; in 2013, the basket's cost was $82; and in 2014, the basket's cost was $90. The value of the CPI in 2014 was:

A) 109.8 and the inflation rate was 16.9%

B) 116.9 and the inflation rate was 16.9%

C) 116.9 and the inflation rate was 9.8%

D) 109.8 and the inflation rate was 9.8%

Explanation:

CPI is consumer price index.  It is used to indicate the inflate rate in the economy.

Calculating the CPI is as below

CPI = current basket prices/ base year basket price  x 100

In this case.

C) 116.9 and the inflation rate was 9.8%

CPI =90/77 x 100

CPI =1.16883x 100

CPI = 116.883

CPI = 116.9

Inflation for a period is measured by taking into account the difference in price from the previous periods.

Inflation for 2014 will be price difference between 2014 and 2013.

i.e., 90 - 82

As a percentage,

The inflation will be 92-8/ 82 x 100

= 8/82 x 100

=0.0975 x 100

=9.756

=9.8%

among other factors, composers started writing dynamic markings in their scores because "new instruments allowed for more dynamic ranges and contrast."

dynamics allude to the loudness or softness of music. dynamics offer an approach to demonstrate articulation in sheet music. they to drive the enthusiastic substance of music through volume and force. maybe you could alter both the volume and the shading profundity on your screen at the same time. we can likewise think about the force side of elements as the quality of a note. a few notes are intended to be played delicately and gently, while others are intended to be played all the more firmly.  

some dynamics markings have a letter 'm,' which remains for mezzo, signifying 'medium.' so a mezzo piano unique stamping resembles this (mp) and intends to play medium calm, while a mezzo specialty dynamic resembles this (mf) and intends to play medium loud.
