Question

To celebrate Halloween, Trisha's class is making candy necklaces. Trisha is helping pass out string from a 50-yard-spool. She gives 30 inches of string to each student. If there are 24 students in her class, how many yards of string will be leftover? 30 POINTS FOR CORRECT ANSWER

Answer 1

Answer:

30 yards of string will remain unused

Step-by-step explanation:

Ok, there are a lot of conversions going on here.

1 yard = 3 feet,

so 50 yards • 3ft per yard = 150 feet of string on the spool

1 foot = 12 inches,

so 150 feet • 12in per foot = 1800 inches of string on the spool

There are 24 students and they each get 30 inches, multiply 24 • 30 to see how much string is used:

24 • 30 = 720 inches of string used

Find how many inches of string is left by subtracting what is used from the original amount:

1800 - 720 = 1080 inches of spool left

To make this faster, instead of dividing by 12 inches per foot and then dividing by 3 feet per yard, I'm just dividing by 36 inches per yard.

1080 ÷ 36 = 30 yards of string remaining

Answer 2

Answer:

she gave out 720 inches of string which is 20 yards so she has 30 yards left on the spool
