the total cost for one dozen donuts includes the cost to make the donuts and the cost of the box create an expression to model that total cost for one dozen donuts where t represents the total surface area of the box in square feet

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
