She deposited $350.00 into the account at the beginning of the year.

Answer:  Keegan did a deposit of  $350.00 at the beginning of the year

Step-by-step explanation:

Hi, to solve this problem we have to analyze the information given:

  • Amount (A) : $360.50
  • Interest Rate (r): 3% = 0.03 (decimal)
  • Time(t)= 1 year

We have to apply the simple interest formula:

  • A = P(1 + rt)
  • 360.5= P (1+ 0.03x1 )

Now we have to calculate the value of the principal amount by solving the formula.

  • 360.5 = P (1.03)
  • 360.5/ 1.03 = P
  • P= 350

Keegan did a deposit of  $350.00 at the beginning of the year.
