Aleena has a savings account that gives 5% annual interest. She deposits $200 that she received on her birthday. Write an equati
ANTONII [103]

Answer:the equation is 200 + 10x

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal or initial amount deposited into the account.

R represents interest rate on the principal

T represents time in years

I = interest after t years

From the information given

T = x years

P = $200

R = 5%

Therefore

I = (200 × 5 × x)/100

I = 1000x/100

I = 10x

Therefore, the equation representing the total amount of money that would be in the account after x years would be

200 + 10x
