Suppose Joe is maximizing total utility within his budget constraint. If the price of the last pair of jeans purchased is $25 and it yields 100 units of extra satisfaction and the price of the last shirt purchased is $20, then, using the rule of equal marginal utility per dollar spent, the extra satisfaction received from the last shirt must be:

A) 2,000 units of utility.
B) 500 units of utility.
C) 100 units of utility.
D) 80 units of utility.

80 units

Explanation:

Given:

Let X is the number of units we need to find

As we know that, the law of equal-marginal utility a consumer spends his or her income among goods so that utilities receive from the amount spent is equal. So we use a simple rule of three:

$25    100 units of utility

$20      X

<=> 25X = 20*100

<=> X = 80 units

Hope it will find you well.

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.
