At the bookstore, Mario bought a magazine for $4, and five books that all cost the same amount. He spent a total of $129. Which equation expresses how much each book cost?

• $x\ =\ 129-4$

• $5x\ -\ 4\ =129$

• $4x\ +\ 5\ =\ 129$

• $5x\ +\ 4\ =\ 129$

Brandon bought a bottle of water for $2. He also bought some hot dogs, h, for $3 each. Brandon did not spend more than $14 on the hot dogs and the bottle of water. Which inequality best represents this situation?

• $3h\ +\ 2\ \le\ 14$

• $3h\ -\ 2\ \le\ 14$

• $3h\ +\ 2\ \ge\ 14$

• $3h\ -\ 2\ \ge\ 14$

Destiny had $150 to spend on 3 pairs of jeans. After buying them, she had $30 left over. What equation expresses how much each pair of jeans cost?

• $\frac{30j}{3}\ =\ 150$

• $3j\ -\ 30\ =\ 150$

• $3j\ +\ 30\ =\ 150$

• $3j\ =\ 180$

Crystal opens a bank account with $30 in it. She adds $20 each month. Write an equation to represent the relationship between the amount of money in her account, a, and the number of months, m.

• a=20m+30

• a=30m+20

• m=20m+30

• m=30m+20

9 increased by m is 15

• m + 15 = 9
• 9  + m = 15
• 9 x m = 15
• 9 + 15 = m
