Let us assume that after n weeks you and your friend is going to have same amount. After n weeks the money in your account will be 20 (initial amt) + 5 (savings each week) * n or simply 20 + 5n Similarly, after n week your friend is going to have 5 + 10n As per the questions these two amounts are same, hence 20 + 5n = 5 + 10n => 5n = 15 => n = 3 (Desired number of weeks) hence, money in each account is 20 + 5*3 = $35 (Second part)
