Answer:
$764.42
Step-by-step explanation:
The account balance is given by the formula ...
A = P(1 +rt)
where P is the principal invested, r is the annual rate, and t is the number of years. Here, we assume 52 weeks in the year, since the time period is given in weeks.
Filling in the numbers, we have ...
A = $750(1 +0.025(40/52)) = $764.42
Darren's investment will be worth $764.42 at the end of 40 weeks.
