I am assuming the problem is asking you to find an equation repersenting the situation.
In this case, realize that 150 will be a constant, and 60 will be attached to the 
variable, since the price of the textbooks changes based on how many textbooks there are.
Thus, the equation is:
Our answer is 60x + 150 = y.
Answer:
The answer would be 76.36
Step-by-step explanation:
You count by 36 by adding at 36 every time u go up :
36, 72, 108,144 , 180 etc
Answer:
the third expression
Step-by-step explanation:
x=10.8
(x2 / 18) + 33.52
10.8 x 10.8=116.64
116.64 divide by 18=6.48
6.48 + 33.52=40
