Question 66898: Use the simple interest formula to find the principal if the
total interest earned was $150 and the rate of interest was 4% for 2 years.
Dollars=P Interest=I Rate of interest=r Time calculated in years=t. Simple interest formula is I=Prt.
Keeping this forumla in mind and the information provided it would seem that 150=P x 0.04 x 2, next step looks like 150=P x 0.08, to get P we will divide 150 by 0.08. This works out to be 1875. So the principal is $1875.
did i do this right?

Yes you did, and keep in mind that you can check your solution in the original eq:
I = 1875 * .04 * 2
I = 150 the given interest
