So, Sierra, this is easier than it seems, I promise.
We want to find the lowest price possible. The lowest-priced tent is normally $68. The most that can be taken from it is 25%.
I like to do percents in different ways. If I take 25% off the price, then my new price is 75% of the original, right? 75% is 3/4, right?
If I draw a circle and divide it into 4 parts and say the whole circle is 68, then how much is each part? 17! We only need 3 of the 4 parts, so that's 51. $51 is the lowest price we can have.
Now we need to find the highest price posdible. The most expensive tent is $119. The least we can take off is 10%.
If we take off 10%, that's 1/10. 1/10 of 119 is 11.9. 119 - 11.9 = 107.1, so the highest price we can have is $107.10.
How do we write all that algebraically? If we say x is the price of a tent bought, it has to be at least $51 but no more than $107.10, or x > $51 and x < $107.10
We can combine these into $51 < x < $107.10.
Hope this helps!
