Answers
Answer:How many centimeters of string does she need? 30 * 30 cm = 900 cmIf 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.
