Why do interest rates on loans tend to be higher in a strong economy than in a weak one?

Credit markets increase in a strong economy, and with increased demand come increased prices.

A strong economy encourages borrowers to take out very long-term loans, which have higher interest rates.

Credit is plentiful in a strong economy, so it is harder to build up the good credit rating necessary for a low interest rate.

People in a strong economy have more money, so they can afford more expensive loans.

An account is opened with $7,595.96 with a rate of increase of 2% per year. After 1 year, the bank account contains $7,746.90. Assuming no deposits or withdrawals are made, which equation can be used to find y, the amount of money in the account after x years? (Round money values to the nearest penny.)

y = 7,746.90(1.02)x

y = 7,746.90(0.02)x

y = 7,595.96(1.02)x

y = 7,595.96(0.02)x
