Problema Solution
Cameron opened a savings account with dollar sign, 1800$1800 that pays no interest. He deposits an additional dollar sign, 140$140 each week thereafter. How much money would Cameron have in the account 46 weeks after opening the account?
Answer provided by our tutors
After 0 weeks (when the account is opened) there is $1,800
After 1 week there is $1,800 + $140
After 2 weeks there is $1,800 + $140 + $140 = $1,800 + 2*$140
After 3 weeks there is $1,800 + 2*$140 + $140 = $1,800 + 3*$140
....
After 46 weeks there is $1,800 + 45*$140 + $140 = $1,800 + 46*$140 = $8,240
After 46 weeks, Cameron will have $8,240 on his account.
