The salads in total are $9.50
The waters in total are $3.30
together the total cost is $12.80
First, convert the 15% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 15%) by 100%. So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $12.80 meal cost is. This is always done by multiplying 0.15 by $12.80, or
0.15 x $12.80=$1.92.
So, the amount of tip you are going to leave is $1.92.
This makes the total cost of your meal (to write on your charge slip or other payment)
<span>$12.80 + $1.92 = $14.72.</span>
An "equation" has a left side, a right side and an equals sign separating the sides. An "expression," by contrast, doesn't have any "sides" and is simply what the name suggests: An algebraic "expression<span>."</span>
Answer:
$18,750
Step-by-step explanation:
Step 1.
150,000 x 1/2 = 75,000
(this is the amount going to his daughter)
Step 2.
150,000 x 3/8 = 56,250
(this is the amount going to his favorite nephew)
Step 3.
75,000 + 56,250 = 131,250
Step 4.
150,000 - 131,250 = 18,750
(this is the amount left over for his only grandson)

Answer:
The value of x is -10.
Step-by-step explanation:
Given : Expression ![3x-8=\frac{8x+4}{2}](https://tex.z-dn.net/?f=3x-8%3D%5Cfrac%7B8x%2B4%7D%7B2%7D)
To find : What is the value of x?
Solution :
Step 1 - Write the expression,
![3x-8=\frac{8x+4}{2}](https://tex.z-dn.net/?f=3x-8%3D%5Cfrac%7B8x%2B4%7D%7B2%7D)
Step 2 - Cross multiply,
![6x-16=8x+4](https://tex.z-dn.net/?f=6x-16%3D8x%2B4)
Step 3 - Take like terms together,
![6x-8x=4+16](https://tex.z-dn.net/?f=6x-8x%3D4%2B16)
Step 4 - Solve,
![-2x=20](https://tex.z-dn.net/?f=-2x%3D20)
![x=-\frac{20}{2}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B20%7D%7B2%7D)
![x=-10](https://tex.z-dn.net/?f=x%3D-10)
Therefore, The value of x is -10.
