Basic Financial Formulas

A commonly used formula for calculating present and future values is

Where FV represents the future value, PV denotes the present value, r signifies the interest rate, and n indicates the number of compounding periods. It’s essential to remember that r and n must correspond to the same compounding duration, e.g. r is compounded monthly while n is expressed in months.

The inquiry seeks to determine the PV necessary as a one-time deposit to achieve a future value of $7,500 in 3 years at an interest rate of 1.5% compounded monthly.

FV=7,500

r=1.5%=0.015

n=3*12=36 months

We have changed n to months since r is monthly compounded. The equation

must be arranged to isolate PV.

Response

Response: the equations are

0.02x + 0.07y = 156

y = 300 + x

Step-by-step explanation:

Let x denote the dollar amount from phone sales made by Josiah.

Let y indicate the dollar amount from his computer sales.

Josiah receives a 2% commission on his phone sales total and 7% on his computer sales. He accumulated a total of $156 in commission, leading to the equation

0.02x + 0.07y = 156 - - - - - - - - - - -1

Furthermore, it’s given that Josiah had $300 more in computer sales than in phone sales, expressed as

y = 300 + x
