Question

A Stack of 50 kitchen serving trays forms a coumn that is approximaetly 7 1/4 inches tall. What is closest to the number of kitchen trays that would be needed to form a column that is 14 inches tall?

Answer 1

Answer:

97 trays

Please follow along below for an explanation.

Step-by-step explanation:

If a stack of 50 kitchen trays is 7.25 inches tall, how many would it take to make a stack 14 inches tall?

The first step is to divide the 7.25/50 to determine the height of each plate.

The answer to this is 0.145 inches per tray.

Now you need to find how many are in 14 inches.

Divide 14 inches by 0.145 inches to find out how many plates are needed.

You will get an answer of 96.55

You can't exactly have 96.55 serving trays so you need to round to the nearest whole number. Because the decimal is greater than 0.5, you round up.

This gets you to 97 serving trays.
