Question

Answer 1

Answer:

It will take 6 weeks for the carpenter to have total of 23 chairs.

Step-by-step explanation:

Given:

A  carpenter makes custom chairs.

He currently has 11 chairs in his showroom.

If he can build 2 chairs each week.

Now, to find the weeks it will take him to have a total of 23 chairs.

So, the carpenter has already 11 chairs in his showroom.

And, he need to have total 23 chairs.

So, the chair remains to build is:

$23-11=12.$

Thus, 12 chairs remain to build by the carpenter.

As, the carpenter can build 2 chairs each week.

Now, to get the number of weeks it will take him to build 12 chairs we divide 12 by 2:

$12\div 2\\\\=6\ weeks.$

Therefore, it will take 6 weeks for the carpenter to have total of 23 chairs.

Answer 2

Answer:

The correct answer is 6 weeks.

Step-by-step explanation:

The carpenter has currently 11 chairs in his show room.

He intend to have a total of 23 chairs.

Therefore the carpenter have to make 23 - 11 = 12 more chairs to meet his expectation of 23 chairs.

Rate at which he makes the chair = 2 chairs per week.

Number of weeks the carpenter would take to make 12 chairs = $\frac{12}{2}$ weeks = 6 weeks.

Thus the carpenter would take 6 more weeks to make 12 extra chairs and thus have a total of 23 chairs.
