To find the number of spools the costume designer should buy, we need to divide the total amount of thread needed by the amount of thread on each spool.
Total amount of thread needed = 20,800,000 centimeters
Amount of thread on each spool = 130 centimeters
Number of spools needed = Total amount of thread needed / Amount of thread on each spool
= 20,800,000 / 130
= 160,000
Therefore, the costume designer should buy 160,000 spools of thread.
A costume designer needs 20,800,000 centimeters of pink thread for a project. If there are 130 centimeters of thread on each spool, how many should she buy?
