To find the full bags of mulch you divide 77.5 by how much can fit in one bag (2.25). There are 34 full bags. Multiply 34 by the price per bag, which is $2.25. The total price of all 34 bags is $76.50.
a. 77 × 0.5 = 38.5
2 × 0.25 = 0.5
38.5 × 0.5 = 19.25
Answer = 19
b. 19 × 2.25 = 42.75
Answer = 42.75
