Answer:
$90.00
Step-by-step explanation:
40% of What is 36?
40/4 = 10 (10%)
36/4 = 9 (9 is 10% of the answer we are looking for)
Multiply both answers (9 and 10) by each other.
You get 90
If this is the equation
-x-1=3x-5
then it should be x=1
Answer:
17
Step-by-step explanation:
Answer:
1 4 /15
Step-by-step explanation:
3/5 + 2/3
the first step is to get a common denominator, 15
3/5 * 3/3 + 2/3 * 5/5
9/15 + 10/15
19/15
new we need to change it to a mixed number
15 goes into 19 one time with 4 left over
1 4/15
Answer:
The profit form a strawberry smoothie is of $26.32, and the profit from a chocolate smoothie is of $26.32.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the profit from a strawberry smoothie.
y is the profit from a chocolate smoothie.
Se sold 24 strawberry smoothies and 5 chocolate smoothies, for a profit of $200.
This means that: 24x + 5y = 200
Today, she made a profit of $300 by selling 30 strawberry smoothies and 11 chocolate smoothies.
This means that 30x + 11y = 300
So we have the following system:
24x + 5y = 200
30x + 11y = 300
I will use the addition method, multiplying the first equation by 5 and the second by -4. So
120x + 25y = 1000
-120x - 44y = -1500
So, adding both equations, we get:
![-19y = -500](https://tex.z-dn.net/?f=-19y%20%3D%20-500)
![19y = 500](https://tex.z-dn.net/?f=19y%20%3D%20500)
![y = \frac{500}{19}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B500%7D%7B19%7D)
![y = 26.32](https://tex.z-dn.net/?f=y%20%3D%2026.32)
And for x:
![24x = 200 - 5y](https://tex.z-dn.net/?f=24x%20%3D%20200%20-%205y)
![24x = 200 - 5(26.32)](https://tex.z-dn.net/?f=24x%20%3D%20200%20-%205%2826.32%29)
![24x = 68.4](https://tex.z-dn.net/?f=24x%20%3D%2068.4)
![x = \frac{68.4}{24}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B68.4%7D%7B24%7D)
![x = 2.85](https://tex.z-dn.net/?f=x%20%3D%202.85)
The profit form a strawberry smoothie is of $26.32, and the profit from a chocolate smoothie is of $26.32.
