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%

yor answer is 7/6 times 5

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
