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.
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.
