Mr. Morales purchases 6 boxes of pencils, 12 boxes of pens, and 4 cases of notebook paper for his classroom. Each box of pencils costs $4.10, each box of pens costs $6.50, and each case of notebook paper costs $105. What is the total cost in dollars of his classroom supplies?

$522.60

Step-by-step explanation:

               pencils:  $4.10 * 6             ===> $24.60

                  pens:  $6.50 * 12           ===> $78

notebook paper:  $105 * 4              ===> $420

pencils + pens + notebook paper = total cost

24.60 + 78 + 420 = 522.60
