since all angles are the same, then the sides must also be the same measure
therefore
6x-3=3x+6=5x
we can solve for x by taking any 2 equations
6x-3=5x
minus 5x both sides
x-3=0
x=3
Equation for one year:
0.0725(400)
But we have 7 years:
7(0.0725(400))
Multiply in the parentheses
7(29) = 203
400 + 203 = 603
You now have $603, and made $203
