We have to calculate how big was Trevor`s initial deposit if he has investment worth $6,774.50. The formula for the simple interest is: I = P * r * t and A = P + I, A = $6,774.50 ( the final investment value ), r = 0.027, t = 22 ( years ). 6,774.50 = P + P * 0.027 * 22; 6,774.5 = P + P * 0.594; 6,774.5 = 1.594 P; P = 6,774.50 : 1.594; P = 4,250. C . $4,250.00.
