Jamie invested $3000, part at 11% interest in a porridge company and part at 8% in a bowl company. she earned $216 more in interest from the 11% investment than she did from the 8% investment. how much did she invest at each rate?

Step-by-step explanation:

Let x represent the amount invested at 11%. Then (3000-x) is the amount invested at 8%. The interest difference is ...

  0.11x - 0.08(3000 -x) = 216

  0.19x -240 = 216 . . . . . . . . simplify

  0.19x = 456 . . . . . . . . . . . . add 240

  456/0.19 = x = 2400 . . . . . the amount invested at 11%

  3000-2400 = 600 . . . . . . . the amount invested at 8%

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
