Michael perez deposited a total of $2000 with two savings institutions. one pays interest at a rate of 6%/year, whereas the other pays interest at a rate of 7%/year. if michael earned a total of $136 in interest during a single year, how much did he deposit in each institution? (let x and y denote the amount of money, in dollars, invested at 6% and 7%, respectively.)

Answers

Answer 1

Answer:

He invested $400 in the account with interest at 6%, while investing $1600 in the account with interest at 7%.

Explanation:

Given that Michael Perez deposited $ 2000 in two different accounts that granted an interest of 6% and 7% per year respectively, and that at the end of the year he obtained $ 136 in interest, to determine how much money he invested in each account it is necessary to perform the following calculation:

2000 = 100

136 = X

((136 x 100) / 2000) = X

13600/2000 = X

6.8 = X

Thus, the benefits obtained were 6.8% per year. Thus, the annual 7% of the account with the highest interest rate must subtract a 0.2% yield, with which Michael Perez invested 2/10 parts of his money in the account with interest at 6% and 8/10 in the account with interest at 7%.

Thus, in the account with interest at 6% he invested $ 400, while in the account with interest at 7% he invested $ 1600.

Imagine you know someone starting off in his or her first career. Based on what you learned in the module, what financial advice would you give this person and what challenges might he or she face?

Answers

Answer:

The most important and basic financial advice we can give to a person starting his career is to only spend as much as the person earns.

Explanation:

Because starting salaries tend to be lower than average, it is not very likely that this person will be able to save, but keeping a balanced personal budget will be very helpful anyway.

A second advice is to avoid debt on consumer goods, and only use debt for long-term investments like a house or a graduate degree. Credit card debt should be specially avoided because of the very high interest rates.

Finally, a third advice is that once this person earns enough to save, to look for safe financial instruments to put his or her money, like a mutual fund or a money market fund.

Which is not the cost of rising unemployment in an economy?

a)Lower Tax Revenues (Government collects less taxes)

b)Higher Benefits Payments

c)Crime, Vandalism, Family Breakdowns, Social Welfare, and Regional Decay in the Society

d)Opportunity Cost of Lost Potential Output

e)Flourishing Economy

Answers

Answer:

e)Flourishing Economy

Explanation:

Unemployment is a scenario where members of the adult population seek job opportunities but cannot get any. Therefore, an unemployed person is a jobless adult who is actively seeking employment.

Unemployed people have no income, which means they do not pay taxes. They may resort to crime to support themselves. Jobless people usually claim unemployment benefits, which is a burden to the government. A jobless person is mostly idle, which is a waste of skill, time, and knowledge.

Unemployment has adverse effects on the economy. It does not support the growth or flourishing of economic activities.
