I dont understand it​

30xy

Step-by-step explanation:

I divided this shape into a square and a rectangle.

Solve:

First I multiplied 2x and 3y

2x*3y= 6xy

Then I multiplied 6x and 4y

6x*4y= 24xy

Then I added them together

24xy+6xy= 30xy

Hope this helps!

they wold be getting 600$ more than what they paid for them at first

because if you multiplied the amount of shirts the bought by the cost of each shirt the you would get 600$ dollars more then the cost when they bought them
