(a)
15 ÷ 3 x 5 = 25
15 ÷ 3 x 2 = 10
Total mass of venison and chicken bought
= 12 u + 5 u + 25
= 17 u + 25
17 u + 25 = 144
17 u = 144 - 25
17 u = 119
1 u = 119 ÷ 17 = 7
Mass of chicken bought
= 5 u + 25
= 5 x 7 + 25
= 35 + 25
= 60 kg
(b)
Mass of venison bought
= 12 u
= 12 x 7
= 84 kg
Answer(s): (a) 60 kg; (b) 84 kg
