1 u + 482 |

- 198 |
| After |
1 u |
1 u + 284 |
(a)
After
Number of macarons that Pamela had = 1 u
Number of macarons that Mrs Kong had = 3 x 1 u = 3 u
Before
Number of macarons that Pamela baked = 1 u
Number of macarons that Mrs Kong baked = 1 u + 482
3 u = 1 u + 482 - 198
3 u - 1 u = 284
2 u = 284
1 u = 284 ÷ 2 = 142
Number of macarons that Pamela baked
= 1 u
= 142
(b)
Number of macarons that Mrs Kong baked
= 1 u + 482
= 142 + 482
= 624
Answer(s): (a) 142; (b) 624
