This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio
so we get

We could have also gotten this using Trig:


Or by recognizing u=v because remaining angle is 45 so this must be isosceles so



1/4 x 900 = 225.00
225.00 is the total
Answer:
3
Step-by-step explanation:
It seems like your question is not complete.
So I will asume that it is like the one in the image.
But probably the answer is not 3 if the range is different from (1-2), eventhough, you just have to follow the same steps.
35% decrease as a multiplier = 1 - 0.35 = 0.65
1900 x 0.65^4 = 802.75
$802.75
