Answer: $15680

Step-by-step explanation:

Principal = Unknown

Time = 5 years

Rate = 9.8%

Simple interest = $7683.20

Simple interest= PRT/100

7683.20 = (P × 9.8 × 5)/100

7683.20 = 49P/100

Cross multiply

768320 = 49P

P = 768320/49

Principal = $15680

Margaret borrowed $15680 to buy the car.
