Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.

Answer:
The difference between the purchase with a debit card and the purchase with a credit card lies in the way of financing the amount to be paid. Thus, in the purchase with a debit card, the money with which the purchased good or service is paid is immediately withdrawn from the bank account of the cardholder, with which the debit card works as a cash payment but without use paper money. On the other hand, when paying with a credit card, said amount is not subtracted from the account, but instead a debt is taken with the bank, which must be paid after a certain period.
