Tessa bought stock in a restaurant for $278.00. Her stock is now worth $339.16. What is the percentage increase of the value of

Natasha2012 [34]

The percentage increase of the value of Tessa's stock is 22%

Step-by-step explanation:

The percentage of increase = $\frac{New-old}{old}$ × 100%, where:

New: is the value after increasing
Old: is the value before increasing

Tessa bought stock in a restaurant for $278.00.

Her stock is now worth $339.16

We need to find the percentage of increase of the value of

Tessa's stock

∵ The initial value of the stock = $278.00

∴ The value of the stock after increasing = $339.16

- Substitute these values in the rule above

∴ The percentage of increasing = $\frac{339.16-278}{278}$ × 100%

∴ The percentage of increasing = 0.22 × 100%

∴ The percentage of increasing = 22%

The percentage increase of the value of Tessa's stock is 22%

X+y=3<br> y+x= 5<br><br> help please

Oksana_A [137]

Solve by elimination ie eliminate x or y from the equations by performing operations on them.
first label the equations , to follow the process.
x - y = 5 ----------------(1)
x+ y = 3 ----------------(2)
If (1) and (2) are added then y will be eliminated.
(1) + (2) gives : 2x = 8 → x = 4
now substitute this value of x into either of the 2 equations and solve for y.
let x = 4 in (1) : 4 - y = 5 → -y = 1 → y = -1
check in (1) : 4-(-1) = 4+1 = 5
check in(2) : 4 - 1 = 3

So your answer is x = 4 , y = -1
