After |
1x4 = 4 u |

(a)
12 ÷ 4 x 7 = 21
12 ÷ 4 x 3 = 9
Total mass of venison and pork bought
= 8 u + 7 u + 21
= 15 u + 21
15 u + 21 = 96
15 u = 96 - 21
15 u = 75
1 u = 75 ÷ 15 = 5
Mass of pork bought
= 7 u + 21
= 7 x 5 + 21
= 35 + 21
= 56 kg
(b)
Mass of venison bought
= 8 u
= 8 x 5
= 40 kg
Answer(s): (a) 56 kg; (b) 40 kg
