Answer each part of the constructed response question. Make sure to clearly label your answer for each part and show all your work. Simple Interest formula: I = Prt where Interest earned (I) is equal to principal amount invested (P) times the interest rate (r) times the amount of time invested (t). How much did Michael invest if he earned $4,800 in interest over 6 years at 8%? Part A: Rearrange the formula for P. Part B: Use the formula from Part A to find Michael's principal investment amount (P).
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
