Answer:
62 newspapers
Step-by-step explanation:
Let s represent the number of Sunday papers sold. Then s/2 is the number of Friday papers sold. The total revenue is ...
1.50s + 0.75(s/2) = 116.25
1.875s = 116.25 . . . . simplify
s = 116.25/1.875 = 62 . . . . . divide by the coefficient of s
62 Sunday papers were sold.

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
