I will have $2721 at the beginning of the eighth year.
The beginning of the eighth year is the end of <em>seven years of investing</em>.
The formula for the future value (FV) of my investment is
FV = <em>C</em>(1 + <em>r</em>)^<em>n</em>
where <em>C</em> = my initial cash
<em>r</em> = the interest rate
<em>n</em> = the number of years
FV = $2000(1.045)^7 = $2722

Answer:
find the actual discount, multiply the discount rate by the original amount 'x'. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price. Solve the equation and find the original amount 'x'.
Step-by-step explanation:
Sale Price = $11.34 (answer). This means the cost of the item to you is $11.34. You will pay $11.34 for a item with original price of $12.60 when discounted 10%. In this example, if you buy an item at $12.60 with 10% discount, you will pay 12.60 - 1.26 = 11.34 dollars.
7.50 X 315 =2362.50 at the lower price
7.75 X 315 = 2441.25 at the higher price
subtract 2362.50 from 2441.25 you get 78.75
