Meg is making necklaces out of leather string. Each necklace requires 25 centimeters of string. Meg wants to make a necklace for each member of her family so she needs a total of 7 necklaces.
How many centimeters of string does Meg need?
If the total cost of the string was $4.41 , what was the cost per metre? Explain your reasoning.
7*25 = 8*25-25 = 200-25 = 175 cm
175 cm = 1.75 meter
$4.41 / 1.75 = dollars/meter
Thank you ^^
To find out how many centimeters of string Meg needs, we can multiply the length required for each necklace by the total number of necklaces. In this case, each necklace requires 25 centimeters of string, and Meg wants to make 7 necklaces. So the total length of string Meg needs is:
25 cm/necklace * 7 necklaces = 175 cm
Therefore, Meg needs 175 centimeters of string.
To find the cost per meter of the string, we need to know the total cost of the string and the length of the string. In this case, we know that the total cost of the string is $4.41, but we need to find the length of the string in meters.
Since Meg needs 175 centimeters of string, we need to convert this length to meters:
175 cm = 175/100 meters = 1.75 meters
Now, we can divide the total cost by the length in meters to find the cost per meter:
$4.41 / 1.75 meters = $2.52 per meter
Therefore, the cost per meter of the string is $2.52.
