A 500 g packet of nuts costs R24. At the same price per gram, what would 2000 g cost?
Answer and explanation
Correct answer: C. R96
- Step 1: 2000 g is 4 times 500 g.
- Step 2: Cost = 4 × R24 = R96.
Answer
R96.
Why not the others: R6: the ratio of masses was inverted. R39: the working contains a slip: the extra mass was added in some unit. R48: the mass was not compared with the original pack size.
