A student states that natural resources could be saved if people made everything they need in labs. What is the main problem with this idea?(1 point) There are not enough synthetic resources yet to make what people need.

People might think it is fine to waste a lot of the materials since they just came from a lab.

The materials made in labs will still pollute the environment and destroy natural resources.

Anything made in the lab requires natural resources to produce it.

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
