Question

Joel has $20. He needs a calculator that costs $12 and some notebooks that cost $2 each.

Part A: Write an inequality that can be
used to find the number of
notebooks,n, that Joel can
afford to buy.

12+2n ≤ 20


PART B: What is the graetest possible
value of n? Show your work and
explain in words how you
determined your answer.

Answer 1

Solve the inequality for n, just like you would an equation. Since it's greater than or EQUAL to, whatever you get for n is the answer.

Subtract 12 from both sides, then divide both sides by 2.
