Aman bought a dozen boxes each with 24 highlighter pens inside for $ 8 each box he repacked these boxes into packages of six highlighters each and sold them for $ 3 per package how much profit did he make?

He brought 12 boxes (dozen) with 24 pens.. okay and each are 8 bucks. 24 x 12 = 288 (pens total)
12 x 8 = $96 (spent total)

6 pens = one package for $3
288 pens divided by 6 ... = 48 packages
48 x 3 = $144 (sold total)

144-96 = $48 (profit)
