(a)
20 ÷ 4 x 5 = 25
20 ÷ 4 x 1 = 5
Total mass of venison and beef bought
= 16 u + 5 u + 25
= 21 u + 25
21 u + 25 = 193
21 u = 193 - 25
21 u = 168
1 u = 168 ÷ 21 = 8
Mass of beef bought
= 5 u + 25
= 5 x 8 + 25
= 40 + 25
= 65 kg
(b)
Mass of venison bought
= 16 u
= 16 x 8
= 128 kg
Answer(s): (a) 65 kg; (b) 128 kg
