Answer:
5000 Australian Dollars
Step-by-step explanation:
To find out how many Australian dollars need to be sold, we first need to find the profit of a single dollar sold.
We will be using the formula for profit, which is:
Profit = Total Revenue - Total Cost
Now we define the available variables.
Total Revenue = 81.40
Total Cost = 80.20
Profit = 81.40 - 80.20
Profit = rs 1.20/dollar
Now we have to find how many dollars we have to sell to get a profit of rs 6000.
We simply divide the amount of profit that we want to the price per dollar.
Total Profit = 6000
Profit per dollar = 1.20
This give us:
6000 / 1.20 = 5000 Australian Dollars.
Yes because if yuo add 12 more your adding 12 more of students to make 24
Answer:
Step-by-step explanation:
I think you are trying to use synthetic division for
divided by x-3
First
x -3 = 0 , make it equal to 0 and add 3 to both sides
x = 3
Then we write all the coefficients and continue with
a pattern of multiply by 3 and add to the next coefficient.
See attachment.
The general rule for difference of two squares is that when factorised it can be written in the form (a+b)(a-b) where a is the square root of the first part of the function and b is the square root of the second part of the function.
From this we can find the square root of x² to find a and the square root of 16y² to find b.
In this case √x²=x and √16y²=4y
Therefore fully factorised it can be written as (x+4y)(x-4y)
