Question

At a yard sale, a woman spent less than $26 on books that were labeled $3 each. Which of the following inequalities models this situation?
A. 26b = 3
B. 3b < 26
C. 3/b < 26
D. 3b > 26

Answer 1

The answer is the second one, B. As the books were worth $3 each, and b stands for the number of books the woman bought, multiplying them would equal how much she spent. As $26 is said to be worth more than this, 26 is greater than 3b.

Answer 2

B. Why?
The women spent "less than $26" => thats equivalent to < 26
and $3 each, 3b, b is the amount of books, 3 is the price per book.

So, B. 3b < 26
