The table shows the loan balance of two different loans each year for 2 years. Determine whether each balance is linear or nonlinear. Then predict which account will have a lower balance in Year 3.

• Loan A balance is linear. Loan B balance is nonlinear. Account A will have a lower balance in Year 3.

• Loan B balance is linear. Loan A balance is nonlinear. Account A will have a lower balance in Year 3.

• Loan A balance is linear. Loan B balance is nonlinear. Account B will have a lower balance in Year 3.

• Loan B balance is linear. Loan A balance is nonlinear. Account A will have a lower balance in Year 3.
