Question

Cheryl has $56 and wants to buy as many notebooks as she can to donate to her school. If each notebook costs $1.60, which inequality shows n, the maximum number of notebooks she can buy with her money?
A) 1.6n greater than or equal to 56
B) 1.6n Less than or equal to 56
C) 56n Less than or equal to 1.6
D) 56n Greater than or equal to 1.6

Answer 1

The answer is B because n is equal to the number of notebooks. you can not exceed the amount of money that you have to buy the notebooks

Answer 2

Answer-

$\boxed{\boxed{B.\ 1.6n\leq 56}}$

Solution-

The amount of money that Cheryl has = $56

The cost of each notebook = $1.60

n = the maximum number of notebooks she can buy with her money

Then cost of n notebooks will be,

$1.60\times n$

As Cheryl has $56, so she can spend any amount less than or equal to $56. She can not spend more than $56, as she does not have more than that.

Hence, the inequality becomes,

$\Rightarrow 1.6n\leq 56$
