Exemplars (from the NaCCA curriculum)
E.g.1 Make mathematical sentences involving linear inequalities from word problems. i. Think of a whole number less than 17 i.e. x < 17 ii. Eight less than the product of -3 and a number is greater than -26. Write and solve an inequality to represent this relationship. i.e.-3x-8>-26 iii. Kwaakye's profit for March of GH₵ 32 was at least GH₵ 12 less than his February profit. What was his February profit? I.e. March profit was at least GH₵12 less than February's profit. GH₵23 ≥ _ 12 + p
