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 of n

"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.
