Answer:

B = 87.08 pounds @ $0.32

A = 22.92 pounds @ $0.08

Step-by-step explanation:

given,

cost of beans (A)= $ 0.08/pound

and another beans cost (B) = $ 0.32 /pound

total weight of the pound = 110 pound

selling price of mixture = $ 0.27/pound

cost of each bean = ?                    

A + B = 110                                

A = 110 - B-------(1)                        

0.08 A + 0.32 B = 0.27 x 110

0.08 A + 0.32 B = 29.7                

Putting value of A                    

0.08(110 - B) + 0.32 B = 29.7

8.8 - 0.08 B + 0.32 B = 29.7

0.24 B = 20.9

B = 87.08 pounds @ $0.32

A = 22.92 pounds @ $0.08

You will need to deposit  $ 10,957 each year until retirement to achieve your retirement goals.

<h3>What is compound interest, and how does it work?</h3>

Compound interest is computed on a loan or deposit based on the starting principle and the preceding period's accrued interest.

Principal(P)=$40,000

(Time period)T=25+15 = 40 year

R=8%

The final balance is $273,938.99 and the total compound interest is $233,938.99.

The amount he has to deposit each year is found as;

⇒$273,938.99/25

⇒ $ 10,957

Hence. you will need to deposit  $ 10,957 each year until retirement to achieve your retirement goals.
