One package of markers has dimensions 6”x8”x1”. what are the dimensions of the box that will hold 30 packages of markers and use the least amount of cardboard

The solution is in the following image

The solution is given in the image below

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

tip=18% of 75.45

     =18/100 * 75.45 = $13.581

Tip = $13.581

The solution is given below

(​1 or 7) ; number of possible outcome = 2

(a, e,​ i, o, or​ u) ; number of possible outcome = 5

So,

Number of possible outcomes = 2 x 5

Number of possible outcome =10

The answer is in the image 

Attendance in jan = 140

Attendance next week = 252

Change in attendance = 252 - 140 = 112

% change = change/Attendance before *100

                = 112/140 * 100

                =80 %
