(a)
9 ÷ 3 x 8 = 24
9 ÷ 3 x 5 = 15
Total mass of beef and venison bought
= 15 u + 8 u + 24
= 23 u + 24
23 u + 24 = 116
23 u = 116 - 24
23 u = 92
1 u = 92 ÷ 23 = 4
Mass of venison bought
= 8 u + 24
= 8 x 4 + 24
= 32 + 24
= 56 kg
(b)
Mass of beef bought
= 15 u
= 15 x 4
= 60 kg
Answer(s): (a) 56 kg; (b) 60 kg
