Answer:
905 - 825 = 80
that means 80 min is between those times,
80 min = 1 hr and 20 min
*WARNING THIS WILL NOT WORK FOR SOME QUESTIONS, I AM DOING A SHORTCUT WAY!!*
Answer: <u><em>1 hr and 20 min has passed from 8:25 to 9:05. </em></u>
The customers would pay 3/4 of the original price because the store is paying for 1/4 of it.

Answer: 800</h3>
======================================================
Work Shown:
(160 with blue eyes)/(500 total) = (x with blue eyes)/(2500 total)
160/500 = x/2500
x = 2500*(160/500)
x = 800
------------
Another approach:
160/500 = 0.32 = 32% of the first group has blue eyes
Assuming this percentage is the same for any group, then,
32% of 2500 = 0.32*2500 = 800 people of the second group are estimated to have blue eyes, of the 2500 total.
Expanded form is when you just write it out.
so 9 cubed becomes:
9×9×9
and 20 squared becomes:
20×20
the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.
