Answer:
Your answer is D p=3.99;$51.87
Step-by-step explanation:
The answer is D. p = 3.99b; $51.87.
In this case first we have to represent the equation and then find the total price of the books in order to find the correct answer. This is:
Total price = p
Number of books = b
Cost of each book = $3.99
This is a case of multiplication were we have to multiply the number of books by the cost of each one to find the total price, this is:
Having this we can calculate the total price of buying 13 books, this is:
The total price of buying 13 books at $3.99 is $51.87.
3rd option is the correct answer
ring volume is 12cm3
Lr ccm=volume of water and ring - Volume of water
ring cubic centimeters =x
x=9.2cm*4.5cm*7cm - 8.8cm*4.5cm*7cm
x=289.2cm3 - 277.2cm3
x=12cm3
$7.80
$2.60 * 3 = $7.80
