Lee Middle School orders 15 textbooks for every 12 students. The table shows how many textbooks the school orders for certain numbers of students. Predict the number of textbooks that the school would order for 72 students.

Students 12, 24, 48, 96, 192

Textbooks 15, 30, 60, 120, 240

Answer: 90 textbooks

Step-by-step explanation:

everytime you multiply the number of students you multiply the books by the same number. to find how many times 72 was multiplied you divide it by 12.

72 : 12 = 6

then multiply the original number of books (15) by 6.

15 * 6 = 90

so for every 72 students the school orders 90 textbooks
