I NEED HELP PLEASE! ANYONE WHO ABOUT THE FIFO METHOD?

Fifo stands for "First In, First Out". It means that if a certain number of people enters a place in a queue, then those people will exit the place in the same order.

For example, think of an elevator with doors on both sides. In 3 people enter from the front door and they exit from the back door, they will exit in the same order that they enter.

The opposite is the so-called FILO (First In, Last Out), in which people leave in the inverse order.

Imagine now an elevator with only one door. The first person who enters will be the farthest from the door, while the last person entering will be the closest. So, he will exit first, and the first person entered will exit last.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
