What annual interest rate must anika bartko earn to have $80,000 increase to $90,000 in two years?

the annual interest rate must be 6.25%

Step-by-step explanation:

The initial amount that Anika Bartko had was $80,000

If the amount increases to $90,000, it means that the amount of interest is 90000 - 80000 = $10000

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents the annual interest rate

T represents time

From the information given,

P = $80000

T = 2 years

I = 10000

Therefore

10000 = (80000 × R × 2)/100

10000 = 1600R

R = 10000/1600 = 6.25%

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
