Answer:
Rashid and Megan need 40 felt patches.
Step-by-step explanation:
Draw a table with number of costumes in the first row and the number of felt patches in the second row.
Note that for 1 costume, 5 felt patches are needed.
For 2 costumes, 10 felt patches are needed
For 3 costumes, 15 felt patches are needed and so o.
So, the pattern in the table is whenever there is 1 increase in the costumes, there are 5 numbers increase in felt patches.
From the table, we can easily identify that the 8 costumes need 40 felt patches.
Hence, Rashid and Megan need 40 felt patches.
