Answer:

280000lb

Step-by-step explanation:

In this question, we shall be calculating the amount of carbon iv oxide prevented from entering the atmosphere.

Generally we know that 1kwh produces 1.37 lbs of Carbon iv oxide in the atmosphere

Now, using a 100 watt light bulb daily for 8 hours, for a year, the amount of Carbon iv oxide produced will be;

100 * 1.37 * 8 * 365 = 40040 lb

Using a 30 watt CFL for 8hrs/ day for a year, we have;

30 * 1.37 * 8 * 365 = 120012 lb

Now calculating the amount of CO2 prevented, we have 40040 - 120012 = 280028 lb = 280000 after rounding up

Answer:

The method we will use to solve applications with linear inequalities is very much like the one we used when we solved applications with equations. We will read the problem and make sure all the words are understood. Next, we will identify what we are looking for and assign a variable to represent it. We will restate the problem in one sentence to make it easy to translate into an inequality. Then, we will solve the inequality.
