Arectangular box is created by cutting out squares of equal sides
of lengths x from a piece of cardboard 10 inches by 15 inches and
folding up the sides as shown in the figure. the volume of the box is
given by v = x(10 – 2x)(15 – 2x). find the volume of the box when
the side length of the square is 3 inches.

Well, the box will have 7in long 4 in wide and 2 in high

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
