After |
2x4 = 8 u |

(a)
12 ÷ 4 x 5 = 15
12 ÷ 4 x 1 = 3
Total mass of venison and pork bought
= 12 u + 5 u + 15
= 17 u + 15
17 u + 15 = 185
17 u = 185 - 15
17 u = 170
1 u = 170 ÷ 17 = 10
Mass of pork bought
= 5 u + 15
= 5 x 10 + 15
= 50 + 15
= 65 kg
(b)
Mass of venison bought
= 12 u
= 12 x 10
= 120 kg
Answer(s): (a) 65 kg; (b) 120 kg
