Write an equation that could be used to answer the question above. First chose the appropriate form. Then, fill in the blanks with the numbers 8, 5, and 133. Let B represent the number of books.

A. _b + _ = _
B. _b - _ = _

Answer 1

Answer: He bought 16 books

Step-by-step explanation: $133-$5=$128 (taking away shipping)

$128/8=16 (separating non-shipping price into groups of $8 to compensate for the cost of books)

A: 8b+5=133

B: 8b-133=5

b=16
