On the east steps the Air Force Band in uniforms of Air Force blue
is playing hard and loud, but - queer -
the music doesn’t quite come through

In the stanza above the poet contrasts the blue uniforms with the lack of music. Discuss how this makes you feel about the playing of the music.
The blue uniforms are patriotic while the lack of being able to hear the music seems like a lack of patriotism.

1. Decrease

Explanation:

Gross profit percentage is the amount of money earned from the sales of goods or rendering of services expressed in percentages. It is the amount earned expressed in percentage after removing the total cost of production from revenue earned.

Formula for calculating

= (Gross profit/Total sales) × 100.

Thus, when there's a decrease in the price of goods with the cost of producing that goods remaining constant, the gross profit percentage decreases. Also, when there's an increase in price with cost remaining constant, the gross profit also increases.
