(a)
25 ÷ 5 x 7 = 35
25 ÷ 5 x 2 = 10
Total mass of chicken and venison bought
= 20 u + 7 u + 35
= 27 u + 35
27 u + 35 = 332
27 u = 332 - 35
27 u = 297
1 u = 297 ÷ 27 = 11
Mass of venison bought
= 7 u + 35
= 7 x 11 + 35
= 77 + 35
= 112 kg
(b)
Mass of chicken bought
= 20 u
= 20 x 11
= 220 kg
Answer(s): (a) 112 kg; (b) 220 kg
