Question

Write formula for each of the following.

1) Simple Interest

2) Profit %

3) Loss​

Answer 1

Answer:

1) Simple Interest : A = P(1+rt)

Explanation :  

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

Use this simple interest calculator to find A, the Final Investment Value, using the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods. Where r is in decimal form; r=R/100; r and t are in the same units of time.

2) When calculating profit for one item, the profit formula is simple enough: profit = price - cost . total profit = unit price * quantity - unit cost * quantity . Depending on the quantity of units sold, our profit calculator can also determine the total cost, profit per unit and total profit

Formula: Loss = Cost price (C.P.) – Selling Price (S.P.) Profit or Loss is always calculated on the cost price. Marked price: This is the price marked as the selling price on an article, also known as the listed price.
