Amusic 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

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!

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
