(a)
4 ÷ 2 x 7 = 14
4 ÷ 2 x 5 = 10
Total mass of chicken and venison bought
= 6 u + 7 u + 14
= 13 u + 14
13 u + 14 = 118
13 u = 118 - 14
13 u = 104
1 u = 104 ÷ 13 = 8
Mass of venison bought
= 7 u + 14
= 7 x 8 + 14
= 56 + 14
= 70 kg
(b)
Mass of chicken bought
= 6 u
= 6 x 8
= 48 kg
Answer(s): (a) 70 kg; (b) 48 kg
