Eliza wants to sell a used car stereo online. From her research on the website she will post to, she found 8 similar stereos listed. She
decides to list her stereo for 20% less than the mean price of the
stereos already for sale on the site. Let a represent the sum of the prices
of the stereos she found in her research. Write an expression to calcu-
late the price she will list as the cost of her stereo.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

=

=

=
