After |
1x4 = 4 u |

(a)
8 ÷ 4 x 7 = 14
8 ÷ 4 x 3 = 6
Total mass of chicken and venison bought
= 8 u + 7 u + 14
= 15 u + 14
15 u + 14 = 59
15 u = 59 - 14
15 u = 45
1 u = 45 ÷ 15 = 3
Mass of venison bought
= 7 u + 14
= 7 x 3 + 14
= 21 + 14
= 35 kg
(b)
Mass of chicken bought
= 8 u
= 8 x 3
= 24 kg
Answer(s): (a) 35 kg; (b) 24 kg
