Final answer:
The discount rate used by the bank in computing the proceeds is approximately 5.94%.
Step-by-step explanation:
To find the discount rate used by the bank in computing the proceeds, we can use the formula for present value:
Present Value = Future Value / (1 + Discount Rate)^n
In this case, the future value is $44,356, the present value is $43,136, and the time period is 90 days (which is equivalent to 90/360 = 0.25 years).
Plugging in the values into the formula, we get:
$43,136 = $44,356 / (1 + Discount Rate)^0.25
Multiplying both sides by (1 + Discount Rate)^0.25, we get:
(1 + Discount Rate)^0.25 = $44,356 / $43,136
Taking the fourth root of both sides, we get:
1 + Discount Rate = ($44,356 / $43,136)^(1/0.25)
Subtracting 1 from both sides, we get:
Discount Rate = ($44,356 / $43,136)^(1/0.25) - 1
Using a calculator to compute the value, we find that the discount rate used by the bank is approximately 0.0594 (or 5.94%).
