Answer: Assuming you mean that the original cost was doubled and now equals $60, the camera costed $30. Assuming the camera's price has been doubled from $60, it is $120. The wording is a bit unclear, so I'm giving you both answers.
Step-by-step explanation: To find half of the price of $60, simply divide it by 2, which gives you $30.
Answer:
$4.34
Step-by-step explanation:
Given the information:
- The original price: $5
- Discount : 20%
- Tax: 8.5%
We can find out the actual price that Diane bought a bunch of balloons that was marked down 20% is:
= the original price (100% - discount rate)
= 5(100% -20%)
= $4
- The tax amount she need to pay is:
= The actual price*tax rate
= $4*8.5%
= $0.34
=> the total cost of the bunch of balloons :
The actual price + tax price
= $4 + $0.34
= $4.34
Hope it will find you well.
Slope = 4/5 because the formula for slope is rise/run. count the x and y units point one and point two are away from each other.
To solve this problem you must apply the proccedure shown below:
1- The formula for calculate the area of this rectangle is:
Where 
is the length and 
is the heigth.
2. Let's call identify the heigth with the variable 
.
3. If the length is 
longer than the heigth, you have:
4. Therefore, you can write the following polynomial expression:
5. If you know the value of the heigth, you can susbstitute it into the polynomial expression shown above and you will obtain the area.
Therefore, the answer is:
