Xavier is buying notebooks for school. The table below shows the number of notebooks he can buy and the total cost. Which equation can be used to find the total cost, y, of n notebooks?
A. 2.41 - n = y
B. 2.41 + n = y
C. 2.41 × n = y
D. 2.41 ÷ n = y​

2.41 * n = y

Step-by-step explanation:

From the table, we can notice that the value;

y/n is a constant for each of the rows

this represents the individual costs of each of the books

So, we have it that;

7.23/3 = 4.82/2 = 9.64/4 = $2.41

So, the books have a unit cost of $2.41

Hence, by multiplying the number of books n by 2.41 we can get the cost y

So mathematically, we have the relation as;

2.41 * n = y

C

Step-by-step explanation:

C. 2.41 × n = y

the correct is answer is a 9-sided polygon!

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
