Answer 1

Answer:

The inequality equation situation for Kevin is $25 - 0.75x \geq 13$ and able to download 16 songs.

Concept:

Inequality is the relationship between two expressions that both use the inequality symbol. The phrases on either side of an inequality symbol are not equal. The phrase on the left should be larger or smaller than the expression on the right, or vice versa, according to this symbol. Relationships between two algebraic expressions that are represented by the inequality symbols are known as literal inequalities.

Given:

Total amount Kevin have = $25

Cost of songs per download = $0.75

After downloading Kevin has leftover amount = $13

Find:

Find the inequality equations which represents Kevin situation?

Solution:

The equation can be expressed as:

$25 - 0.75x\geq 13\\-0.75x\geq 13 - 25\\-0.75x \geq -12\\x\leq 16$

So, Kevin has downloaded 16 songs.

Therefore, the inequality equation that represent Kevin situation $25 - 0.75x \geq 13$ and able to download 16 songs.
