Sharon earns$25 per item she sells plus a base salary of $100 per week.  Write and solve an inequality to find how many items she must sell to earn at least $700 per week.  Provide your conclusion as a complete sentence.

triciaal · Answer

Amount earn = cost per item *number of items  added to base pay
to earn at least $700  means Amount earned >or = $700
let amount earned = E, number sold = n and base pay = B
then 
E = 25 n + 100
25 n + 100 >/= 700

solve for n  then your conclusion will say 
In order for Sharon to earn at least $700 per week selling items at $25 each with a base pay of $100 she needs to sell at least "n" items.
