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.
Answer:
7
Step-by-step explanation:
We want to evaluate the fraction below for x = 3. We will put the value of x to be 3:

The answer is 7.
Are you sure you've copied down the original problem exactly as given? i38 = 38i can't be simplified. Perhaps you meant i^38, which is a different matter.
Note that i^38 = i^32 * I^4 * I^2.
Note that i^0, i^4, i^8, etc., all equal 1. Therefore,
i^38 = (1)(1)i^2 = 1*(-1) = -1 (answer)
Answer:
b = -3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6b+14=−7−b
6b+14=−7+−b
6b+14=−b−7
Step 2: Add b to both sides.
6b+14+b=−b−7+b
7b+14=−7
Step 3: Subtract 14 from both sides.
7b+14−14=−7−14
7b=−21
Step 4: Divide both sides by 7.

b= -3
If you divide 16 by 2 you get 8, so, 8 teams payed $50, while the other half payed $60.
Hope this helps. ^_^
(If you're gonna add them up it's 8x60=480 + 8x50=400=880) :P
