Information:Juan plans to bulid a bookcase to store his paperback books DVDs and CDs he has lumber that he will use for the sides and back of the bookcase the bookcase will have 5 shelves in each shelf will be two and a half feet long

Question: juan bought lumber that is 18 feet long.
a.does he have enough lumber to make the five shelfs? If not, how much more does he need if so, how much will be left over?

Please HELP ASAP if you can!!!!!!!

5 * 2 1/2 = 12 1/2 feet of lumber needed for the shelves.

18 - 12 1/2 = ________ feet left over

Oh ok thx!!!!

You're welcome.

To determine if Juan has enough lumber to make the five shelves, we first need to calculate the total length needed for all the shelves.

Given that each shelf will be two and a half feet long, we can multiply this length by the number of shelves:

2.5 feet x 5 shelves = 12.5 feet

So, Juan needs 12.5 feet of lumber for all the shelves.

Now, we can compare this with the length of lumber Juan bought, which is 18 feet.

If 12.5 feet is less than or equal to 18 feet, then Juan has enough lumber. However, if 12.5 feet is greater than 18 feet, he will need additional lumber.

12.5 feet <= 18 feet

Since 12.5 feet is indeed less than or equal to 18 feet, Juan has enough lumber to make the five shelves.

To calculate how much lumber will be left over, we subtract the required length (12.5 feet) from the total length of lumber (18 feet):

18 feet - 12.5 feet = 5.5 feet

Therefore, Juan will have 5.5 feet of lumber left over after constructing the bookcase.
