ed needs to purchase 5.6 meters of tape. if each roll contains 80 cm and costs 5.00 what is the total cost of the tape ed must buy
5.6 meters x 100 cm/meter = 560 cm.
Now, we have the same units.
divide 560 by 80 cm to get the numer of rolls you have to buy.
Multiply that answer times $5 per roll
thank you I UNDERSTAND IT NOW
To find the total cost of the tape Ed must buy, we need to calculate the number of rolls he needs and then multiply it by the cost per roll.
First, let's convert the given length of tape from meters to centimeters, since the roll size is given in centimeters:
5.6 meters = 5.6 * 100 (1 meter = 100 centimeters)
= 560 centimeters
Next, we need to determine the number of rolls Ed needs to purchase. Since each roll contains 80 centimeters of tape:
Number of rolls = Total length of tape / Length of tape in each roll
Number of rolls = 560 cm / 80 cm
Number of rolls = 7
Ed needs to purchase 7 rolls of tape.
Finally, we can find the total cost by multiplying the number of rolls by the cost per roll:
Total cost = Number of rolls * Cost per roll
Total cost = 7 * $5.00
Total cost = $35.00
Therefore, the total cost of the tape Ed must buy is $35.00.
