Atablet computer costs $189.69 including tax. it is marked up 30%.

what is the final price of the tablet computer after it is marked up?

$56.91

$132.78

$219.69

$246.60

Find out the what is the final price of the tablet computer after it is marked up.

To prove

As given

A tablet computer costs $189.69 including tax.

It is marked up 30%.

30% is written in the decimal form.

= 0.30

Marked up price  = 0.30 × 189.69

                             = $56.907

Final price of the tablet computer after it is marked up = Computer cost including tax + Marked up price

Final price of the tablet computer after it is marked up = $189.69 + $56.907

Final price of the tablet computer after it is marked up = $246.597

Final price of the tablet computer after it is marked up = $246.60(Approx)

Therefore the final price of the tablet computer after it is marked up is $ 246.60 (Approx) .

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".
