Orla · Answer

Answer:   5 gifts     Step-by-step explanation:     Given information:   Cost of one gift = $4  Total money = $50  Money left after purchasing gifts = at least $28     Let x = greatest number of gifts James can buy    Create an inequality with the given information:  ⇒ 50 - 4x ≥ 28     Solve the inequality   Add 4x to both sides:  ⇒ 50 - 4x + 4x ≥ 28 + 4x  ⇒ 50 ≥ 28 + 4x  Subtract 28 from both sides:  ⇒ 50 - 28 ≥ 28 + 4x - 28  ⇒ 22 ≥ 4x  Divide both sides by 4  ⇒ 22 ÷ 4 ≥ 4x ÷ 4   ⇒ 5.5 ≥ x  ⇒ x ≤ 5.5    We must  round down  to 5 as if James buys 6 gifts, he will only have $26 remaining.  Therefore, the greatest number of gifts James can buy is  5 gifts .
