Solution · 5 marks
- 13 + 2 + 5 = 10
- 280 ÷ 10 = 8
- 33 × 8 = 24 chocolate cakes
- 42 × 8 = 16 lemon cakes
- 55 × 8 = 40 fruit cakes
- 624 × 2.00 = 48.00 from chocolate cakes
- 716 × (3/4) = 12 lemon cakes sold
- 812 × 1.70 = 20.40 from lemon cakes
- 940 × (7/8) = 35 fruit cakes sold
- 1035 × 2.40 = 84.00 from fruit cakes
- 1148.00 + 20.40 + 84.00 = 152.40
