The school principal orders 6 new chalkboard for each grade. There are 3 grades in the school. Each new chalkboard cost $98. What is the total cost for the new chalkboards? Explain how you found your answer.

6 per grade, 3 grades in school. Multiply these 2 numbers to find out how many total chalkboards the principal is ordering.

6 (3) = 18, the principal is ordering 18 new chalkboards.

Since each chalkboard costs $98, multiply 18 by $98 to find the total cost of all the chalkboards.

18 (98) = 1764. The new boards cost will be $1,764.

Final Answer:

The total cost of the new chalkboards will be $1,764.

6 chalk boards x 3 grades = 18 chalk boards

18 chalk boards x $98 per chalk board = $1,764
