Raymond took a $20,000 loan from a bank at an interest rate of 15% per year for a 3-year period. What is the total amount that he would have to payback the bank? Please dont put the answer in a file

9000

Step-by-step explanation:

If you divide 20000 by 100 I multiplied by 15 and multiplied that by 3 tell me if it was right.

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".
