Answer: 27 rows contain 25 vines.
Step-by-step explanation:
Let x represent the number of rows that contain 20 vines.
Let y represent the number of rows that contain 25 vines.
Sarah plants 760 vines in rows containing either 20 vines or 25 vines. This means that
20x + 25y = 760- - - - - - - - - - -1
There are 3 times as many rows containing 25 vines as there are rows containing 20 vines. This means that
y = 3x
Substituting y = 3x into equation 1, it becomes
20x + 25 × 3x = 760
20x + 75x = 760
95x = 760
x = 760/95
x = 9
y = 3x = 3 × 9
y = 27
So if it is simple interest then
basically you are looking for the interest paid so
5%=5/100=0.05
assuming that the interest is calculated yearly
(12000 times 0.05) times 6 because 6 years so
if you calculate that out then you get 3600
Mai paid $3600 total
Answer:
80%
Step-by-step explanation:
Please consider the complete question:
Micah is preparing for a piano recital. He practices for 50 minutes on Monday and 90 minutes on Wednesday. By how much did she increase the time she practiced each day?
We will use percent change formula to solve our given problem.
![\text{Percent change}=\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times 100\%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20change%7D%3D%5Cfrac%7B%5Ctext%7BFinal%20value%7D-%5Ctext%7BInitial%20value%7D%7D%7B%5Ctext%7BInitial%20value%7D%7D%5Ctimes%20100%5C%25)
Upon substituting our given values, we will get:
![\text{Percent change}=\frac{90-50}{50}\times 100\%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20change%7D%3D%5Cfrac%7B90-50%7D%7B50%7D%5Ctimes%20100%5C%25)
![\text{Percent change}=\frac{40}{1}\times 2\%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20change%7D%3D%5Cfrac%7B40%7D%7B1%7D%5Ctimes%202%5C%25)
![\text{Percent change}=80\%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20change%7D%3D80%5C%25)
Therefore, Micah had increased the time by 80%.
