Answer:

38

Step-by-step explanation:

Subtract the amount it costs to make from the amount Ben makes.  divide 450 by 12 (30-18) and get 37.5.  You can't make half an item, so round up.

The minimum number that Ben should sell to reach his goal is 38 manipulatives.

Further explanation

Ben's goal is $450

Each manipulative cost $18

The selling price of manipulative is $30 each

Question:

The minimum number he can sell to reach his goal?

First, we need to calculate the actual amount that Ben made from selling math manipulative. This actual amount is the difference between the selling price and the cost for making manipulative.

[tex]\boxed {30-18 = 12 }\\[/tex]

The profit he get for each manipulative is $12

If Ben's goal is $450, so the minimum number he should sell is:

[tex]\boxed {=\frac{450}{12} = 37.5 }[/tex]

It's impossible to make only half of manipulative, so we rounded the number to 38 manipulatives.

So, Ben should sell at least 38 manipulatives to reach his goal.
