Key Concepts

Future Value under Simple Interest

The future value under simple interest is calculated by taking the principal and adding the interest accrued linearly over time. In contrast to compound interest where interest is earned on accumulated interest, simple interest adds a fixed percentage of the original principal over each time period, leading to a linear function. This concept explains why the provided function is of the form 1000 + (interest per month)*t.

Interest Rate

The interest rate is the proportion of the principal that is paid as interest per time period. In the context of simple interest, the monthly interest rate multiplied by the initial investment gives the amount of interest earned each month. Determining the monthly interest rate involves matching the term in the linear function with the product of the principal and the rate.

Linear Functions

Linear functions describe relationships where the change in the dependent variable is constant relative to the change in the independent variable. In the context of simple interest, the future value increases by a constant amount each period, represented as the slope of the linear function, which in the provided equation corresponds to the monthly interest portion.
