Stacy opens an account with a deposit of $100. She deposits an additional $25 every week after opening the account. Determine how much money will be in her account after 15 weeks.

$450

Explanation:

after 15 weeks, stacy would have deposited a total of $25 × (15 - 1) = $350. (remember to subtract 1 from the 15 weeks since she did not deposit $25 during the week she opened the account, but only after that.)

now, we need to add this to the original deposit: $100 + $350 = $450.

therefore, after 15 weeks, there would be $450 in her account.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
