Answer:
x = ± 8
Step-by-step explanation:
Given
4x² - 256 = 0 ( add 256 to both sides )
4x² = 256 ( divide both sides by 4 )
x² = 64 ( take the square root of both sides )
x = ± = ± 8
Solutions are x = - 8, x = 8
Current Account Balance = $1,624.35
Initial Deposit = $975
Interest Rate (Simple) = 3.7% simple interest
Interest Earned = Current Account Balance - Initial Deposit
⇒ Interest Earned = $1,624.35 - $975
⇒ Interest Earned = $649.35
Now the Formula for Simple Interest is:
Simple Interest = ×, where P is the initial deposit, R is the rate of interest and T is the time period
⇒ 649.35 =
⇒ T =
⇒ T = 18
Hence, Jeremiah has had the account for 18 years.
