Coleen is making 30 necklaces out of leather stings. each necklace requires 30cm of sting. how many centimeters of string does she need? if the total cost of the string was $4.41, how much did she spend per meter?

How many centimeters of string does she need?

30 * 30 cm = 900 cm

If the total cost of the string was $4.41, how much did she spend per meter?

4.41 / 9 = $0.49 per meter

So 30 necklaces with 30cm of string each, and the total cost was $4.41, but we have to find out how much each meter cost. Wow this problem is a little confusing.

To find the total centimeters of string she needs, we do 30 x 30, which is 900. So she needs 900cm of string.

Now, we have to find how much string is per meter. 1 meter is 100cm, and we know that she needs 900cm, so she needs 9 meters of string. Now, we divide 4.41 by 9, giving us 0.49.

So she needs 900cm of string, and it costs $0.49 per meter.
