Sid paid $6.80 for wrapping paper and $7.35 for ribbon. He wrapped identical gifts for all of his cousins. Sid wrote the expression (6.80 + 7.35) / 8 to help him calculate how much it cost him to wrap each gift. How many gifts did Sid wrap? Explain.

Sid wrapped 8 gifts.

Look at the equation Sid wrote to caclulate the cost to wrap each gift. (6.80 + 7.35) / 8. 6.80 represents the total paid for wrapping paper. 7.35 represents the total amount paid for ribbon. Knowing that information, using the equation, and knowing who Sid wrapped gifts for, we can infer Sid wrapped gifts for 8 cousins.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
