You want to retire on the equivalent of $50,000 per year in today's money. Inflation is expected to be 3%. You will retire in 30 years. You will earn 10% annually on your investments from not till retirement and you will earn 8% during retirement (which is expected to last 20 years). How much do you need to save per month in order to fund this retirement?

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".

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .
