Sean deposits 30% of every paycheck into a savings account. he receives a paycheck for $300.

I'm assuming you want to find how much money Sean put into his account.

To find the amount he put into the savings account, multiply the percentage (as a decimal) and multiply it by 300. 

30%=.3

300*.3= 90

Sean put 90 dollars in his account.

I hope this helps!
