Question

A total of 8000 was invested into accounts at 5 percent and 3 point 5 percent. How much

was invested into each account if the total interest for the year was $327.50.

Answer 1

$4,833.33 at 3.5%

$3,166.67 at 5%

5X+3.5Y = 32,750

X+Y = 8000

X=8000-Y

5(8000-Y)+3.5Y=32750

solve for Y, then X
