Mary would like to buy a laptop computer with an original price of $964.60. Which coupon should she use? 50 % off or save $400.00

We will do better using the 50% off

Step-by-step explanation:

First find the price with the coupon

964.64 -400 = 564.60

Now find the price with 50% off

50% off means that we will pay 100-50 = 50 percent

964.60*50% =

964.60*.50

482.30

We will do better using the 50% off

hi there!

how can i assist you?

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".
