The answer is B) 200mm. Check the image for the workings
Answer:

Step-by-step explanation:
we know that

----> 
see the attached figure to better understand the problem
Triangles ABD and BCD are similar by AA Similarity Theorem
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional
so

substitute the given values



simplify

I did x - 10 =290
+10 +10
-------------
x = 300 so they took $1.00 a day
ANSWER:
50.88
STEP BY STEP
First you would do 64 x .25 which is 16
Then you would take the 16 away from 64 so it would be 48
Then you have to add the tax so it would 48 x .06 = 2.88
Finally you would add the 2.88 to 48 which is 50 .88
