Elena receives $95 per year in simple interest from three investments totaling $2100. Part is invested at 3%, part at 4% and part at 5%. There is $1000 more invested at 5% than at
4%. Find the amount invested at each rate.
The amount invested at 3% is $
the amount invested at 4% is $
and the amount
invested at 5% is $

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
