Your class sells a box of oranges to raise $500 for a field trip.You earn $6.25 for each box of oranges sold.Write and solve an inequality that represents the number of boxes your class must sell to meet or exceed the fundraising goal.

Respuesta :

To do this, find the slope, y-intercept, and your goal. 

Your goal is 500. 
Your slope is 6.25 per orange. 
Your y-intercept is 0 (you don't start out with anything.)

So, the inequality is [tex]500 \leq 6.25x[/tex].
You would do 500÷ 6.25= 80

80 boxes of oranges were sold.
