Marco was shopping for markers and lead pencils. The cost of markers is $4, and the cost of each lead pencil is $3. If Macro can
never [62]

This shows that Marco can buy at most 5 pencils

<h3>Inequalities</h3>
  • Let the price of each pencil Marco can  buy be "x"

If the cost of markers is $4, and the cost of each lead pencil is $3 with at most $15 spent, hence;

  • 4 + 3x ≤ 15

Subtract 4 from both sides

3x  ≤ 15

x ≤ 15/3

x ≤ 5

This shows that Marco can buy at most 5 pencils
