Hey there, if you want to know the tax of 40 dollars. The answer is going too be 43.20. Or if you want to know just the tax its going to be 3.20.
The way i did this was to multiply 40 times 8 since each tax is 8 cents.
One major problem is that you're not keeping the units like I showed you.
I think you have everything there, except that I have no idea what that '168'
is all about.
Here it is with the units:
(1million seconds / 1)x(1min/60sec)x(1hr/60min)x(1 day/24hr)x(1 yr/365da)
= (1,000,000 x year) / (60 x 60 x 24 x 365) = <em>0.03171 year</em>
Except for that screwy mysterious '168', you have everything there,
and in the right place. Again, I'm going to say that you didn't realize
it, because you dropped all the units and suddenly all you saw was a
bunch of numbers in front of you.
Is it subtract 228? if so then 3-5 equals -2. -2-8 equals -10. -10-228 equals -238
Answer:
they are congruent
Step-by-step explanation:
they have the same points
The total charges for the first club as a function of the number of rentals (x) are
... f1 = 25 + 2.50x
The total charges for the second club are
... f2 = 3.25x
We want to find x so that f1 < f2.
... f1 < f2
... 25 + 2.50x < 3.25x
.. 25 < 0.75x . . . . . . . . . . subtract 2.50x
... 25/0.75 < x . . . . . . . . . divide by the coefficient of x
... 33 1/3 < x
You must rent 34 videos or more to make the first club more economical.
