Answer:
$9.38
Step-by-step explanation:
The pounds of roast beef that Marine bought = 2.5
The cost of a pound of the roast beef = $3.75
The amount of money paid be Marine can be determined by multiplying the pounds of roast beef bought by its cost per pound.
i.e amount paid = number of pounds of roast beef bought x cost per pound
= 2.5 x $3.75
= $9.375
The amount paid = $9.38
Therefore, the total amount of money paid by Marine for 2.5 pounds of the roast beef is $9.38.
Answer:
width of one box = 1.25 inches
Step-by-step explanation:
Given data:
12 congruent boxes
Length = 25 inches
height = 2 feet
Volume = 9000 cubic inches
First change the height into inches
1 foot = 12 inches
therefore 2 feet = 24 inches
Volume = Length * width * height
9000 = 25 * width * 24
9000 = 600 * width
width = 9000/600
width = 15 inches
width of one box = width of all boxes / number of boxes
width of one box = 15/12
width of one box = 1.25 inches
