The following problem is worded like Example 4 in the​ video, but using different quantities. How can​ $36,000 be​ invested, part at​ 6% annual simple interest and the remainder at​ 4% annual simple​ interest, so that the annual simple interest earned by the two accounts is​ equal? Fill in the table and set up an equation that could be used to solve for the unknowns​ (do not actually​ solve). Use Example 4 in the video as a model for your work.
