A farmer paid $500 per month for deliveries over 10 months. For the other 2 months of the year, he paid $600 per month. Which numerical expression can be used to find the total the farmer paid for deliveries this year?

Multiply each monthly payment by the number of months it was paid: $500 for 10 months is represented by 500(10), and $600 for 2 months is represented by 600(2). Adding these amounts gives the total paid for the year, so the correct expression is 500(10) + 600(2).
