Sabah has $450 to pay for college textbooks. She expects to pay about $75 per book. Her friend told her that 4 of them can be checked out of the library for free. Complete the equation below to find the total number of books that Sabah can get for her classes. Use b to represent the total books.

she can get 4 books for free and spend 2 more books 75 each her left over money is $300.

I believe it would be 10 books?

Step-by-step explanation: because 450/75=6 and since 4 are free, then 6+4=10 b

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✌✌✌
