Cheryl has 56 dollars and wants to buy as many notebooks as she can to donate to her school. If each notebook costs 1 point 6 0 dollars , which inequality shows n , the maximum number of notebooks she can buy with her money?
Answer
A
1 point 6 n is less than or equal to 56
B
56 n is less than or equal to 1 point 6
C
56 n is greater than or equal to 1 point 6
D
1 point 6 n is greater than or equal to 56
Explanation
Each notebook costs $1.60, so buying n notebooks costs 1.60n dollars. That total cannot be more than Cheryl’s $56, giving the inequality 1.60n ≤ 56. Choice D states this condition.
