Answer: They need 18 teachers more.

Step-by-step explanation:

Hi, to solve this problem, first, we have to divide the expected number of children (14,700) by 70.

14,700 / 70 = 210 groups of 70 children

We obtain that they are expecting 210 groups of 70 children each. Since the school district needs 3 teachers for every 70 children, we have to multiply the number of groups (210) by the number of teachers per group (3).

210 x 3 = 630 teachers

We obtained the total number of teachers needed for 14,700 children.

Since at this time the district has 612 teachers, to find the teachers missing we have to subtract the actual number of teachers (612) to the number of teachers needed (630).

630 - 612 = 18

They need 18 teachers more.
