Sara opened a savings account at a bank. The table below shows the exponential relationship between the time t, in years, since Sara opened the account and the total amount d, in dollars, in the account. Time t (years) Total amount d (dollars) 0 670.00 1 674.02 2 678.06 If Sara made no additional deposits or withdrawals, which of the following equations best represents the relationship between t and d?
- 1d = 670(0.006 + t)
- 2d = 0.006(670 t )
- 3d = 670(1 + 0.006) t✓
- 4d = 0.006(1 + 670) t
Correct answer
d = 670(1 + 0.006) t
