You entered kente invested a total of $8000. he invested part of the money for 2yr in a stock fund that earned the equivalent of 6.5% simple interest. he put the remaining money in an 18 month certificate of deposit that earned 2.5% simple interest. if the total interest from both investments was $855 , determine the amount invested in each account?

Step-by-step explanation:

Given,

Kente invested part of money  for 2 yr in stock fund that earned the equivalent of 6.5 % simple interest.He put remaining money in a 18 month certificate of deposit that earn of 6.5%simple interest.

Let he invested in stock fund be$ x. Remaining money =$(8000-x)

∴He got interest from stock fund was =

                                                        =$   [here P =x , R = 6.5% and t = 2 yr]

                                                         =$  

Again he got interest from deposit was =

                                                               =$       [here P = (8000-x), R=2.5% and t =]                              

                                                                =$

According to problem

⇔

⇔18.5 x =171000 - 60000

⇔x =

⇔x = 6000

So he invested in stock fund was = $6000

and in certificate of deposit was =$(8000- 6000)= $ 2000

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
