Fig. 18.7
A player puts two seeds in the first cup, four
in the second, six in the third and so on. How
many seeds will be required altogether if the
player continues to the 24th cup in this way?​

1) Find the unit rate    - In this case the problem already gives us the unit rate.
2) There are multiple ways of solving this problem but since i am a visual learner i choose to create a table.

Multiply the number of rolls by the unit rate to find how many rolls you can get for  $5.75
