Size Price per PumpkinSmall $1.15

Medium $3.60Large $5.25

Our class is planning a trip to the Pumpkin Patch. We have earned $53.29 to spend at the Pumpkin Patch. If we are allowed to get ANY COMBINATION of different sized or same sized pumpkins, how many different combinations could we get? Mathematically justify all combinations.

Solutions:

Since we don’t have to spend exactly $53.29, what would we call these number sentences?

Inequalities

Take 2 minutes in your team to define an inequality.

An inequality is a mathematical sentence that uses one of the inequality symbols to state the relationship between two quantities.An inequality is like an equation, but

instead of an equal sign (=) it has one of these signs:

< ≤ > ≥

In your groups, list as many words/phrases as you can think of that make you think of each of these symbols.

< ≤ > ≥

Let’s look at some real life examples where you see these words and/or symbols!

There is a play area at the Salisbury Mall but it’s only for children.

Must be

under 36

inches to

play.

The play area has a height restriction where you must be

inequality that represents how much weight, w, could be added to the trampoline without breaking.

You shovel snow for your neighbors and earn more than $50.

Write an inequality to represent how much money you earned

shoveling snow.
