Answer:
D
Step-by-step explanation:
<h2>Answer:</h2>
Chlorine tablets cost $54
pH test kit cos $6.6
<h2>Explanations:</h2>
Given the following parameters
Price of a bucket of chlorine tablets = $90
Price of a pH test kit = $11
Total price of chlorine tablet and test kit = $90 + $11
Total price of chlorine tablet and test kit = $101
If the manager uses a coupon that applies a 40% discount to the total cost of the two items, the amount paid in total will be;
Simplify the result to have;
Get the money paid for each item after discount;
For the bucket of chlorine;
For the price of pH test kit;
Hence the price of chlorine tablets is $54 and while the price of the pH test kit is $6.6
Answer:
The correct answer is C.
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 250 million
Future Value (FV)= 500 million
Growth rate (g)= 1% per year
<u>First, we need to calculate the number of years required for the population to double:</u>
n= ln(FV/PV) / ln(1+g)
n= ln(500/250) / ln(1.01)
n= 69.66 = 70 years
It will take 70 years for the population to double.
Answer:
$135000
Step-by-step explanation:
Lets assume the price of the house = x
So, (3.5% of x) = $4725
=> 3.5x/100 = $4725
=> 3.5x = $472500
=> x = $472500/3.5 = $135000
Therefore the price of the house = $135000
