Before |
3x4 = 12 u |
5 u |
+ 10 |

Change |
- 1x4 = - 4 u |
- 4 u |
- 8 |

After |
2x4 = 8 u |
1 u |
+ 2 |

(a)
8 ÷ 4 x 5 = 10
8 ÷ 4 x 1 = 2
Total mass of venison and beef bought
= 12 u + 5 u + 10
= 17 u + 10
17 u + 10 = 61
17 u = 61 - 10
17 u = 51
1 u = 51 ÷ 17 = 3
Mass of beef bought
= 5 u + 10
= 5 x 3 + 10
= 15 + 10
= 25 kg
(b)
Mass of venison bought
= 12 u
= 12 x 3
= 36 kg
Answer(s): (a) 25 kg; (b) 36 kg
