Before |
2x5 = 10 u |
8 u |
+ 24 |
96 |
Change |
- 1x5 = - 5 u |
- 5 u |
- 15 |
|
After |
1x5 = 5 u |
3 u |
+ 9 |
|
(a)
15 ÷ 5 x 8 = 24
15 ÷ 5 x 3 = 9
Total mass of beef and pork bought
= 10 u + 8 u + 24
= 18 u + 24
18 u + 24 = 96
18 u = 96 - 24
18 u = 72
1 u = 72 ÷ 18 = 4
Mass of pork bought
= 8 u + 24
= 8 x 4 + 24
= 32 + 24
= 56 kg
(b)
Mass of beef bought
= 10 u
= 10 x 4
= 40 kg
Answer(s): (a) 56 kg; (b) 40 kg
