To solve the problem, we need to determine the total cost Eli will incur when he buys notebooks and a calculator, and then set up an inequality based on his budget.
- The cost of the calculator is $24.
- Each notebook costs $2, so if Eli buys \( n \) notebooks, the cost of the notebooks is \( 2n \).
- Eli's total spending would then be \( 2n + 24 \).
Since Eli only has $37 to spend, we need to ensure that his total spending is less than or equal to that amount. This gives us the inequality:
\[ 2n + 24 \leq 37 \]
Therefore, the correct response from the options given is:
2n + 24 ≤ 37
(2 n plus 24 is less than or equal to 37)
