The owner of a bookstore ordered 75 copies of a book and paid $1,350. The owner of another bookstore also ordered the same book and paid $1,080 for 60 copies. What is the unit price, in dollars, of the book they ordered? help

$18

Step-by-step explanation:

I did the following expressions:

1,350 / 75 = 18

1,080 / 60 = 18

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
