You walk into a clothing store and see a shirt you would like to buy is on sale. It is 30% off the
original price of $30.00. How much are you
saving? How much will you pay for the shirt
before taxes?
:

Step-by-step explanation:

30.00*30%=9 off

30-9=21.00

Alright so n represents a number. 3n means that that numbness has been multiplied by 3. 3n = 3 times n. It’d be -14, -13, -12, -11 etc etc all the way up to 6. It’s saying that 3n can’t be -15 but it can be 6 because the line under the arrow means equal to. If you’ve ever done those crocodile hands it’s basically like the crocodile eats the bigger number. Which is why for 15 < 3n. It’s “eating” 3n because it’s a bigger number. If you need anymore clarification, you can message me
