A concrete estimate is 8.90 cubic yards before waste. Add a 15 percent waste factor. What is the calculated total rounded to two decimal places, before any supplier delivery-increment adjustment?
Correct Answer
B) 10.24 cubic yards.
8.90 × 15% = 1.335 cubic yards of allowance. Total = 8.90 + 1.335 = 10.235 cubic yards, or 10.24 rounded to two decimal places. The 9.79 choice uses 10%, not 15%. The other quantities do not follow the supplied factor. A supplier’s minimum delivery increment is outside this arithmetic exercise.
Why This Is the Correct Answer
8.90 × 15% = 1.335 cubic yards of allowance. Total = 8.90 + 1.335 = 10.235 cubic yards, or 10.24 rounded to two decimal places. The 9.79 choice uses 10%, not 15%. The other quantities do not follow the supplied factor. A supplier’s minimum delivery increment is outside this arithmetic exercise.
