- 1x5 = - 5 u |
- 5 u |
- 20 |

After |
4x5 = 20 u |
3 u |
+ 12 |

(a)
20 ÷ 5 x 8 = 32
20 ÷ 5 x 3 = 12
Total mass of venison and chicken bought
= 25 u + 8 u + 32
= 33 u + 32
33 u + 32 = 329
33 u = 329 - 32
33 u = 297
1 u = 297 ÷ 33 = 9
Mass of chicken bought
= 8 u + 32
= 8 x 9 + 32
= 72 + 32
= 104 kg
(b)
Mass of venison bought
= 25 u
= 25 x 9
= 225 kg
Answer(s): (a) 104 kg; (b) 225 kg
