- 1x3 = - 3 u |
- 3 u |
- 12 |

After |
3x3 = 9 u |

(a)
12 ÷ 3 x 5 = 20
12 ÷ 3 x 2 = 8
Total mass of venison and chicken bought
= 12 u + 5 u + 20
= 17 u + 20
17 u + 20 = 173
17 u = 173 - 20
17 u = 153
1 u = 153 ÷ 17 = 9
Mass of chicken bought
= 5 u + 20
= 5 x 9 + 20
= 45 + 20
= 65 kg
(b)
Mass of venison bought
= 12 u
= 12 x 9
= 108 kg
Answer(s): (a) 65 kg; (b) 108 kg
