Question

a music store sold 10 to the 3rd power CDs and 10 to the second power CD players if each CD cost $12 and each CD player cost $35 what was the store's total earnings

Answer 1

Hello keirabug, I am here to answer your question:

Since 10^3 is the same as 10*10*10, or 1000, and each CD is worth 12$, then 1000 * 12$ is equal to 12000$

But for the CD players, it's 10^2 or 10*10, which gives us 100, and each CD player is worth 35$, so 100 * 35$ is equal to 3500$

And then we do an addition to add the prices like this: 12000$ + 3500$ = 15500$

So the answer is 15500$

Hope this helped you!
