Decrease = initial price - final price

% decrease = [ (initial price - final price)  / initial price ] *100

% decrease =[ (2.89 - 2.83) / 2.89] * 100 =  2.08, which can be rounded to 2.1

Answer: 2.1 %

2.83 to 2.89's percentage of decrease is....
   this is how you calculate this. You first use 2.89 minus 2.83. The answer is 0.06. Then use 0.06 to divide with 2.89. The anser is 0.020.For it to turn into a percentage number, times 0.020 with a hundred. And the answer is 2. So it is a 2 percent decrease. I didn't know how to round it though.

Step-by-step explanation:

Find the diagram attached

Complete Question:

In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?

Sicne triangle STR is isosceles, hence the base angles are equal. Let the base angles be y

y+y+104 = 180

2y = 180-104

2y = 76

y = 38degrees

Since <STR = y, hence the measure of <STR = 38degrees
