Step-by-step explanation:
45+45
90
I guess is the answer
Answer:
Out of all the choices given A. seems to fit best.
The initial value is 500 so the beginning should be A(n) = 500
The rate of increase is 4% so you would put that into decimal form of 0.04
Then you plug in 0.04 into (n - 1) and since we know that it is increasing you would put (1 + 0.04)
And the question asked to find the account's balance at the beginning of year 5 so plug 5 into n in the equation
A(n) = 500(1 + 1.04)^5 = 608.33
Hope this helps!
we'll proceed along the same lines as the previous one.
the cost of the boots is 90.10 and that includes 6.25% sales tax, so if "x" is the 100%, then 90.10 is really the 106.25%, because is including the extra 6.25%.

so if that's the cost of each boot, without tax, then the markup will be 88.8 - 50.88 = 37.92.
if the 100% is 88.8, how much is 37.92 off of it in percentage?

The Answer would be 2.8 because when you subtract -16 - 8 you get -24... then you divide that by 2 and you should have -12 + 25 / 5 + 1.... from there you can move the one from the end and add it to 25 and you get -12 + 26 / 5.... and all you have to do is simple math there... -12 + 26 = 14... and 14 / 5 == 2.8
ANSWER == 2.8
Hope that Helped
