Eggs were $2.05 per dozen on january 1 and $2.00 per dozen on february 1. what percent did the price increase during january?

2.5%

Step-by-step explanation:

The price increased from 2 to 2.05. So the increase was:

2.05 - 2 = 0.05 dollars

Now, to find percentage increase, we use the formula below:

Where

New is the latest price (here it is the increased price of 2.05)

Old is the previous price (here it is the less price of 2.00)

Now, we substitute and find:

So the price increase was 2.5%

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".
