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 $

so what is the question

step-by-step explanation:

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
