Answer:

  • $450,000 at 10%
  • $50,000 at 9%

Step-by-step explanation:

Let x represent the amount invested at 10%. Then the total interest earned per year is ...

  0.10x + 0.09(500,000-x) = 49,500

  0.01x = 49500 -45000

  x = 4500/0.01 = 450,000

$450,000 was deposited in the 10% account; $50,000 was deposited in the 9% account.

five more than the product of a number n and 8 is at least 100. Write an inequality that can be used to find all positive values
hjlf

"More than" indicates addition, and "product" indicates multiplication.



The inequality is:



5 + 8n >= 100



Now we can solve for all positive values of n:



5 + (-5) + 8n >= 100 + (-5)



8n >= 95



8n/(8) >= 95/(8)



n >= 11.875



So all positive values of n include everything between 11.875 and positive infinity, inclusively.
