Explain the difference between budgets, credit cards, payday loans, and debit cards.

Well, a Budget is an estimate of income and expenditure for a set period of time. A Credit Card allows the holder to purchase goods or services on credit(not directly out of their account/charged for monthly payments + interest). Payday Loans is a type of short-term borrowing where an individual borrows a small amount at a very high rate of interest.  Finally, a debit card allows for instant withdrawal of cash from your bank account.

This is a pretty on point question because all we need to do is replace 's' in the equation with '35'.the calculation will be9.95 + 0.30s = c9.95 + 0.30 (35) = c9.95 + 10.5  = cc = 20.45
