Step-by-step explanation:

Given9 apples and 9 bananas cost £2.432 apples and 3 bananas cost £0.69To findCost of an apple and a bananaSolutionApple  = aBanana = b

Equations

9a + 9b = 2.43 ⇒ a + b = 2.43/9= 0.272a + 3b = 0.69 ⇒ 2(a + b) + b = 0.69 ⇒ 2*0.27 + b = 0.69 ⇒ b = 0.15a = 0.27 - 0.15 = 0.12

So the answer

Cost of apple =  £0.12Cost of banana = £0.15
