Hi! SO this is a simple interest question. The formula is I=PRT, but they already give you the interest. It's easy. Insert the #'s into the formula, so: I = Interest P = Principle R = Rate T = Time 264=p * 6% * 2 6% in decimal form would be 0.06 So it would be: 264 = p * 0.06 * 2 Multiply 0.06 and 2 and it equals 0.12 Then u have 264 = p * 0.12 Divide both sides by 0.12 since you are multiplying and you get 2200. Therefore Elsa borrowed $2,200 Hope this helps!
