Guessing and checking isn't the best solution, so I will demonstrate it another way.
Let x be the width. We know that the length is then 2x+5.
So, 2(x+2x+5)=100
3x+5=50
3x=45
So, x=15.
Therefore, the rectangle is 15 centimeters wide.
Guessing and checking could also work. Once you plug in a value, if it is less than 100, than increase you number. The other way works as well.
Answer: Joanna will have 275.4 and Zinaya will have 360.
Joanna Equation: 1,530 x .06 = 91.8
91.8 x 3 = 275.4
Zinaya Equation: 1,500 x .08 = 120
120 x 3 = 360
Hope this helps!!
