Mental accounting can be used to explain(A) higher savings in separate retirement accounts;(B) high willingness to spend on cred
Vlada [557]

Answer:

(D) all of the above.

Step-by-step explanation:

Mental accounting refers to this ability to organize your budget, to think about your money by separating it into different expenditure items. Your brain differentiates money based on how you got it and how you plan to spend it. In other words, you are creating some sort of mental piggy bank where you put your money which will be used for such and such an expense.

Mental accounting can be used to explain how higher savings are derived with various retirement accounts; how high clients purchasing a particular product are willing to spend on credit cards and also explains why brokers hold depreciating stocks longer than appreciating ones due to the mental thought that such depreciating stock will rise at a future time.

A newspaper carrier has $5.40 in change. He has six more quarters than dimes but five times as many nickles as quarters. How man
BigorU [14]
X= number of dimes
x+6= number of quarters
5(x+6)= number of nickels
$5.40= 540 cents

Add the number of each coin and set it equal to the total in cents.


x + (x + 6) + 5(x + 6)= $5.40
multiply 5 by parentheses; change dollar total to cents

x + (x + 6) + (5 * x) + (5 * 6)= 540

x + (x + 6) + 5x + 30= 540
combine like terms

7x + 36= 540
subtract 36 from both sides

7x= 504
divide both sides by 7

x= 72 dimes

x + 6= 78 quarters

5(x + 6)= 390 nickels


CHECK
72 + 78 + 390= 540
540= 540


ANSWER: There are 72 dimes, 78 quarters and 390 nickels.

Hope this helps! :)
