larry mitchell invested part of his $27,000 advance at 2% annual simple interest and the rest at 6% annual simple interest. If his total yearly interest from both accounts was $860, find the amount invested at each rate

X=$4,000 INVESTED5%.

28,000-4,000=$24,000 INVESTED  3%.

Step-by-step explanation:

PROOF:

.05*4,000+.03*24,000=920

200+720=920

920=920

Step-by-step explanation:

Let x is the amount at 2%, then 27000 - x is the amount at 6%.

The total interest is:

The amount at 6% is:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

you save $70

discount would be 35% off
