Using the formula from question 3, find h when v = 141.3 and r = 3. use pi = 3.14.

question 3. the formula i = p r t gives the amount of simple interest (i) earned by investing principle ( p ) for rate ( r ) over a period of time ( t ). solve this formula for p, and find p if r = 0.035, t = 5 and i = $350.
