Question

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.

Answer 1

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
`500 \leq 6.25x`.

Answer 2

You would do 500÷ 6.25= 80

80 boxes of oranges were sold.
