Naomi deposited money into a savings account that is compounded quarterly at an interest rate of 6%. She thinks this quarterly r
Amiraneli [1.4K]

Answer:Yes, Naomi is incorrect.

Explanation: For explain this we can consider an example - Let us suppose Naomi deposited 100 rupees in her saving account at the rate 6% for 1 year .

Now, if the interest is quarterly then according to the formula

compound interest =P(1+\frac{r/4}{100} )^{4n} -P where r is the rate annually and n is the number of years.

so CI=100(1+\frac{6}{100})^4 -100 ( here the rate is already given in quarterly)

CI= 100(1.06)^4-100= 1.26247696-100=26.247696 rupees=26(approx)

Now, if the compound interest is 1.25 per month then again from the formula-

CI=P(1+\frac{r/12}{100})^{12n}-P

CI= 100(1+\frac{1.25}{100})^{12}-100= 100(1.16075452)-100=16.075452=16(approx)

zalisa [80]

Answer:

 Number pencils Ava bought = 2

Explanation:

 Price of pen = 2 $

 Price of pencil = 1 $

 Total money spent = 12 $

 Let the number of pen be a and number of pencil be b.

  2 a + b = 12   -----------------------------------Equation 1

 We have, she bought 3 more pens than pencils

   a - b = 3   --------------------------------------  Equation 2

  Equation 1 +Equation 2,  

           2 a + b +  a - b = 12 + 3

                 3a = 15

                   a = 5

   Substituting in  equation 2

                 5 - b = 3

                b = 2

    Number pencils Ava bought = 2
