A savings account is started with an initial deposit of $700. The account earns 1.5% interest compounded
marusya05 [52]

Answer:

  (a)  A = 700×1.015^t

  (b)  36.2 years

Step-by-step explanation:

(a) Each year, the account value is multiplied by (1 + 1.5%) = 1.015. Repeated multiplication is signified using an exponent. In t years, when the account has been multiplied by 1.015 t times, the account value will be ...

  A = $700×1.015^t

__

(b) You want to find t when A=$1200. Logarithms are involved.

  1200 = 700×1.015^t . . . . use 1200 for A

  1200/700 = 1.015^t . . . . . divide by 700

  log(12/7) = t×log(1.015) . . . . . take logarithms

  log(12/7)/log(1.015) = t ≈ 36.2 . . . . divide by the coefficient of t

It will take about 36.2 years for the account balance to reach $1200.
