Answer:
money owed (in order): $850, $870.40, $891.29, $912.68
Step-by-step explanation:
The formula is
money owed = amount owed the previous week + amount owed previous week × interest rate (in decimal form)
so thats:
money owed = amount owed the previous week + amount owed previous week × 0.024
we can simplify that to:
money owed = amount owed the previous week x (1.024)
after 0 weeks:
$850 (just started, no interest added)
after 1 week:
$870.40
after 2 weeks:
$891.29
after 3 weeks:
$912.68
