Sylvia bought a 6-month $1900 certificate of deposit. at the end of 6 months, she received a $209 simple interest. what rate of interest did the certificate pay? show all of your work.

Step-by-step explanation:

We are given that Sylvia bought a 6-month $1900 certificate of deposit.

Time of deposit = 6 months of a year.

Let us assume rate of interest = R% per year.

Formula of simple interest I = PRT, where P is the bond amount, R is the rate of interest per year and T is the time in years.

Plugging values I=209, P= 1900, R= R%  and T= in above formula, we get

209 = 1900×R×

On simplifying right side, we get

209=950R

Dividing both sides by 950, we get

R= 0.22

Converting 0.22 into % by multiplying by 100, we get 22%.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

answer: 88
