Answer:

x = $ 16,000 , y = $13,000 z= $11,000

Step-by-step explanation:

given,

Investment amount $40,000

three investments yielding = $3,500

three investments are 7%, 9%, and 11%

second and third are $3,000 and $5,000 less than the first

0.07 x + 0.09 y + 0.11 z = $ 3,500

x + (x - 3000 ) + (x - 5000) = $ 40,000

3x = $48,000

x = $ 16,000

y = 16000 - 3000 = $ 13,000

z = 16000 - 5000 = $ 11,000

the investment by each

x = $ 16,000 , y = $13,000 z= $11,000

Next one is x + 4

Now, we can write the word problem as:

$x+x+2+x+4 \leq 33$

Now we solve:

$x+x+2+x+4 \leq 33\\3x+6 \leq 33\\3x \leq 27\\x \leq 9$

So, x is less than or equal to 9, so it can be
