28 x 75% = 21
Jenna ordered 21 large shirts.
Log (7/4) is equivalent to log (7.7/4.4), therefore it's log(7.7) - log(4.4), or...
2.0142 - 1.4816 = 0.5326
I don't have the measurements, but the lqbel would be a rectangle so you need to find its length and height (the length being the circumference of the can and the height being the height of the can)
In my opinion the ages for drinking/smoking should not be raised to 21. While I am not a fan of either and they almost never lead to good things, it just seems odd to me that a person can fight for his country at 18, but can't smoke or drink.
The answer is 3h.
Because 3h is like 3 x H
