(b)
I think the correct answer among the choices presented above is option B. Average is the sum of all the data divided the number of data added. From the statement, we have 3 prices to be added and divided by 3. Therefore, the average is calculated as
<span>($32 + $45 + $39) ÷ 3</span>
Answer:
Step-by-step explanation:
m (x) = (x+ 5) / (x -1) and n(x) = x - 3.
Hence
but n is a function and n = x-3. Now, replace value of n on m (n)
simplify it
since (m . n) (x) is a fraction function, its domain will be all x such that the denominator is NOT 0. That is
among options, only C has the same denominator with 
Hence their domains are the same.
Discounted by 25% means he paid 75% of the original price:
80 x 0.75 = $60
Now multiply the sale price by 1 + tax rate:
60 x 1.05 = 63
He paid $63 total.
