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

Answer:

$n=\frac{8}{3}$ or $n = 2\frac{2}{3}$

Step-by-step explanation:

Multiply both sides of the equation by $\frac{10}{3}$

$(\frac{10}{3}) (\frac{3}{10})*n= (\frac{10}{3})(\frac{4}{5})$

Simplify both sides of the equation.

$n=\frac{8}{3}$ or $n = 2\frac{2}{3}$

Round the mixed number to the nearest whole or half. 11 5/6

Luba_88 [7]

11 5/6 as a decimal would be 11.83. Then, rounding that to the nearest whole number would be 12. Giving you an answer of 12.
