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.

Hope this helps!
Answer:
Book value= $62.83
Step-by-step explanation:
Giving the following information:
A motorcycle bought for $10,000 depreciates continuously at 9% per annum.
<u>First, we need to calculate the depreciation of seven years:</u>
FV= PV*{[1+(-i/100)]^n}
FV= 10,000*{[1+(-0.09/100)]^7}
FV= $9937.17
Book value= 10,000 - 9,937.17
Book value= $62.83
In a - 3 = 15, the value of a HAS to be 18.
In a - 3 is greater than or equal to 15, the value of a is any value that is 18 or higher.
¿Es esta una opción múltiple o es una pregunta explicativa? Lo siento estoy confundido.
