Nikitich [7]

Answer:

The total sale price that Gechina paid was $5,274.71.

Step-by-step explanation:

Given that Gechina Galvez shopped at a department store during the end-of-summer sale in which all luggage was marked down 35 percent, and she purchased a suitcase that regularly sells for $74.95, a garment bag that regularly sells for $8,000, and a tote bag that regularly sells for $39.99, in order to know the total sale price, the following calculation has to be made:

100 - 35 = 65

(8,000 + 74.95 + 39.99) x 0.65 = X

8,114.94 x 0.65 = X

5,274.71 = X

Therefore, the total sale price that Gechina paid was $5,274.71.

the front and back are two 5x3 rectangles

the left and right are just two 3x7 rectangles

and the top and bottom are just two 5x7 rectangles

so, just get the area of each, sum them up, and that's the area of the rectangular prism and thus of the box, and that's how many in² she will need.
