Answer:
$64222.22
Step-by-step explanation:
If we call the original value as x, we can write:
1445 = x * (0.15)² (Note: We write 1 - 0.85 = 0.15 and not 0.85 because 0.85 is the decay factor)
1445 = 0.0225x
x ≈ 64222.22
Sam's solution is incorrect. the correct answer is x=3
Yes,you can.
-- If it's a rectangle, make it more square ... make the length and width
more nearly equal.
-- No matter what shape it is, make it more like a circle. The circle
has the most possible area inside the smallest possible perimeter.
53.24-34.99=18.25
$1 will buy 20 minutes of long distance calling
x$18.25 = 365 minutes @ $34.99
$132-$34.99=$97.01
20x97=1,940 minutes
minimum=365 minutes
maximum=1,940 minutes
Hope this helps.
The last one is rational because it is a terminating decimal.
