Name: SYSTEMS MINI PROJECT INTRO: You are going to use your technology to research 2 items you would like
to buy. One item needs to be about $2.50 and the other $4. You are going to buy a total of 80 items. You
have a budget of $250 to spend. EBay and Amazon are great sites to find your items!
1. Research 2 items you would like to purchase. Write down what you are buying next to the
respective cost. (4 pts)
$2.50
ITEM A (x)
ITEM B (y)
$4
2. Write an equation that represents the total number of items you can buy using the variables (x)
and (y). Use the data from the intro to determine what the total number of items you are able
to purchase.
"Total" equation is:
(4 pts)
how many items you can buy based on the cost of each item

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
