Acarpenter uses 65 shelves to make 13 bookcases. she uses the same number of shelves fo each bookcase. are 32 shelves enough to build 6 more bookcases.

Yes there is enough. Every bookcase will have 5 shelves. 5sheleves ×6 bookcases= 30 shelves in total meaning that she will have two shelves left over after making 6 bookcases.

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
