(a)
10 ÷ 5 x 7 = 14
10 ÷ 5 x 2 = 4
Total mass of pork and venison bought
= 25 u + 7 u + 14
= 32 u + 14
32 u + 14 = 174
32 u = 174 - 14
32 u = 160
1 u = 160 ÷ 32 = 5
Mass of venison bought
= 7 u + 14
= 7 x 5 + 14
= 35 + 14
= 49 kg
(b)
Mass of pork bought
= 25 u
= 25 x 5
= 125 kg
Answer(s): (a) 49 kg; (b) 125 kg
