Answer: Phone C

Using quick mental math, we can do 8% of 10 to get 0.8, which is close to the value of 0.0845*10. Also fairly quick is moving the decimal point over 1 spot to the right and we go from 0.0845 to 0.845 and that rounds to 0.8 when rounding to one decimal place. Recall that 8.45% = (8.45/100) = 0.0845

If you want to compute out the four results with a calculator, then it would look like this:
0.0845*20 = 1.69
0.0845*25 = 2.1125
0.0845*10 = 0.845
0.0845*18 = 1.521
and this shows that no other result (but choice C) is close to 0.8

So that's why the answer is choice C

kozerog [31]

Answer:

The Customer Acquisition Cost for each customer in demographic group 1

The correct option is c

The Customer Acquisition Cost for Group 2

The correct option is b

Step-by-step explanation:

From the question we are told that

The marketing expenses per month for targeting the first group is $E = \$ 30,000$

The marketing expenses per month for targeting the second group is $F = \$ 60,000$

The number of customers for the demography of group 1 that will be attracted is N = 1000

The number of customers for the demography of group 2 that will be attracted is M = 1500

Generally the customer acquisition cost for group 1 is

$K = \frac{E}{ N}$

=> $K = \frac{30000}{ 1000}$

=> $K = \$ 30$

Generally the customer acquisition cost for group 2 is

$Z = \frac{F}{ M}$

=> $Z = \frac{60000}{ 1500}$

=> $Z = \$ 40$
