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,

.

75(b - 4) = 450

Step-by-step explanation:

Given that :

Total amount to spend on books = 450

Total number of books = b

Cost per book = 75

Number of free books = 4

Hence, the number of books sabah will have to pay for will be :

Total Number of books - number of free books

b - 4

Cost of books purchased will be ;

Cost per book * number of books ;

75 * (b - 4)

Total cost = 450

Hence, we have ;

75(b - 4) = 450

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
