Answer:

I'm not sure but according to my knowledge when you raise a number less than zero it gives you a non-complete and also negative number so I think the right answer might be

-0.015625 or -1/64

and 64

I'm again repeating that I'm not sure.

Monica deposits $400 into a savings account that pays a simple interest rate of 4.4%. Paul deposits $500 into a savings accou

DIA [1.3K]

Answer:

From the above calculation it is clear that The interest earn by Monica is less than the The interest earn by Paul , so Monica is wrong

Step-by-step explanation:

Given as :

The principal amount deposited by Monica in account = $ 400

The rate of interest = 4.4 % at simple interest

The time period = 1 years

Let The interest earn by Monica = $ x

From simple interest

Simple Interest = $\dfrac{\textrm principal\times \textrm rate\times \textrm time}{100}$

Or, $ x = $\dfrac{\textrm $ 400\times \textrm 4.4\times \textrm 1}{100}$

Or, x = $ 17.6

So, The interest earn by Monica = x = $ 17.6

Again

The principal amount deposited by Paul in account = $ 500

The rate of interest = 3.6 % at simple interest

The time period = 1 years

Let The interest earn by Paul = $ y

From simple interest

Simple Interest = $\dfrac{\textrm principal\times \textrm rate\times \textrm time}{100}$

Or, $ y = $\dfrac{\textrm $ 500\times \textrm 3.6\times \textrm 1}{100}$

Or, y = $ 18

So, The interest earn by Paul = y = $ 18

∴ As The interest earn by Paul $>$ The interest earn by Monica

Hence from the above calculation it is clear that The interest earn by Monica is less than the The interest earn by Paul , so Monica is wrong Answer

A teacher decides to purchase a new car and considers two options. Option one is the new Zoomba for $60,000 with an expected dep

Lady bird [3.3K]

The teacher chose option 2, the Starfish and it was valued at $35,200 after two months.

Step-by-step explanation:

Step 1; The Zoomba is priced at $60,000 and has an expected depreciation of 2% per month. So the annual depreciation is 12 months * 2% per month = 24% per year. The teacher plans to keep either car for two years do total depreciation is 2 years * 24% depreciation per year = 48 % in two years.

Value of car after two years = Buying price - Depreciation amount

= $60,000 - 48% of $60,000 = $60,000 - 0.48*$60,000 = $31,200

The car will be valued at $31,200 after two years. To determine how much value it has retained we divide the value in two years to the current value i.e $31,200 divided by $60,000 which equals 0.52 (52% of initial price)

Step 2; The Starfish is priced at $40,00 and will depreciate $200 every month. For a year it will depreciate 12 months * $200 per month = $2,400 a year. So for a total of two years a depreciaition of $4,800.

Value of car after two years = Buying price - Depreciation amount

= $40,000 - $4,800 = $35,200

The car will be valued at $35,200 after two years. To see the retained value we divide the depreciated value by the current value i.e. $35,200 divided by $40,000 which equals 0.88 (88% of the initial price)

Step 3; Of the two options, the Starfish retains more of its value over two years. So the teacher chose the Starfish over the Zoomba.
