Greg earns $14 per hour at his office job, along with a $25 weekly bonus. The following inequality represents his earnings on hi

Neporo4naja [7]

Answer:

Greg worked more than 20 hours.

Step-by-step explanation:

Let's solve the inequality for $h$ so we know how many hours Greg worked:

Step 1. Subtract 25 from both sides of the inequality

$14h+25>305$

$14h+25-25>305-25$

$14h>280$

Step 2. Divide both sides by 14

$\frac{14h}{14} >\frac{280}{14}$

$h>20$

We can conclude that Greg worked more than 20 hours.
