Student A starts with $100 in the bank and makes $5 a day. Student B starts with $50 and makes $7 a day. Assuming the students save their money, when will they have the same amount of money ?
Hello,
As h(x) is a bijection,
range(h(x))=dom(h^(-1)(x))={0,1,2,3}
Answer C
So the initial question is x / 113 = 3.14 (we're keeping it a smaller decimal for now)
What you should do first is multiply both sides by 113
Your answer should be x = 354.82
Round this up to x = 355. <-- This is why we only used 3.14 at the start
Now check your work:
x / 113 = ?
355 / 113 = 3.14159265358979... which essentially is pi
The given inequality is equivalent to
.. |p| < (9 +7)/4
which is represented by the 1st selection.
