a) Explanation Procedure used: Rounding Whole Numbers: “To round to a certain place: Step 1: Locate the digit in that the place. Step 2: Consider the next digit to the right. Step 3: If the digit to the right is 5 or higher, round up. If the digit to the right is 4 or lower, round down. Step 4: Change all digits to the right of the rounding location to zeros”. Calculation: Note that, the details about the three days teacher’s conference are listed in the below table. The cost to attend a three day-teacher’s conference $245 The cost for a hotel room $169 Number of teachers 489 Number of rooms 315 From the table, observe that price for three-day conference is $245. Round the numeral 245 to the nearest ten by using the above procedure. Here, the digit in the tens place is 4, which is located by using an arrow as shown below. 2 4 5 ↑ Note that, the digit which is next to the right of the tens place is 5. Thus, by step 3 of above procedure, the digit 4 tens will round up to 5 tens. By step 4, change all digits in the numeral 245 to the right of the tens digit to zero. That is, the rounded value of 245 is 250. Therefore, the rounded value of three-day conference is $250. From the table, observe that price for hotel room is $169. Round the numeral 169 to the nearest ten by using the above procedure. Here, the digit in the tens place is 6, which is located by using an arrow as shown below. 1 6 9 ↑ Note that, the digit which is next to the right of the tens place is 9. Since the digit 9 is higher than 5, by step 3 of above procedure, the digit 6 tens will round up to 7 tens. By step 4, change all digits in the numeral 169 to the right of the tens digit to zero. That is, the rounded value of 169 is 170. Therefore, the rounded value on hotel room is $170. From the table, observe that the number of teachers is 489. Round the numeral 489 to the nearest ten by using the above procedure. Here, the digit in the tens place is 8, which is located by using an arrow as shown below. 4 8 9 ↑ Note that, the digit which is next to the right of the tens place is 9. Since the digit 9 is higher than 5, by step 3 of above procedure, the digit 8 tens will round up to 9 tens. By step 4, change all digits in the numeral 489 to the right of the tens digit to zero. That is, the rounded value of 489 is 490. Therefore, the rounded value of the total number of teachers is 490. From the table, observe that the number of hotel rooms is 315. Round the numeral 315 to the nearest ten by using the above procedure. Here, the digit in the tens place is 1, which is located by using an arrow as shown below. 3 1 5 ↑ Note that, the digit which is next to the right of the tens place is 5. Thus, by step 3 of above procedure, the digit 1 ten will round up to 2 tens. By step 4, change all digits in the numeral 315 to the right of the tens digit to zero. That is, the rounded value of 315 is 320. Therefore, the rounded value of the total number of hotel rooms is 320. In order to find the total cost which spent for the three day-teacher’s conference, multiply the rounded value of the cost of the three day-teacher’s conference and the number of teachers attended the conference b) To determine To estimate: The amount spent by the teachers by rounding to the nearest hundred.
