Answer:
a
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
3r = 10 + 5s
r = 10
3(10) = 10 + 5s
30 = 10 + 5r
20 = 5r
r = 4
First solve the return in each
price per unit
Return = number units sold x price
per unit
Return1 = 5000 units x Php 900
Return1 = php 4,500,000
Next is solve the other price per
unit
Return2 = number units sold x
price per unit
Return2 = (5000 + 1500 units0 x (
php 900 – 100)
Return2 = php 5,200,000
So the php 800 per unit will have
greater return
Answer
A) 2 ln 2 - 2 ln 3
Explanation
Using the laws of logarithms:
ln (x/y) = ln (x) - ln (y)
ln (4/9) = ln (4) - ln (9)
This can be written as
ln (2^2) - ln (3^2)
Another law is:
ln (n^m) = m ln(n)
So finally:
2ln (2) - 2ln 3
