The question, in short

Solve two money problems: find the price of one muffin from a total of £4.74 with a £1.80 cake, and find the maximum apples Caitlin can buy with £5.

Summarised in our own words. Use the official paper for the exact wording and any diagrams.

Part (a) · 3 marks

Given 2 muffins and 1 carrot cake cost £4.74 and the cake costs £1.80, find the cost of each muffin.

  1. 14.74 − 1.80 = 2.94
  2. 22.94 ÷ 2 = 1.47

Answer£1.47

Part (b) · 3 marks

With £5, apples at £0.25 and oranges at £0.30, and twice as many apples as oranges, find the greatest number of apples.

  1. 1For every 1 orange she buys 2 apples: one set costs 2 × 0.25 + 0.30 = £0.80
  2. 2Number of whole sets = 5 ÷ 0.80 = 6.25, so 6 sets
  3. 3Apples = 6 × 2 = 12
