| Before |
1 u |
1 u + 445 |
| Change |

- 166 |
| After |
1 u |
1 u + 279 |
(a)
After
Number of macarons that Natalie had = 1 u
Number of macarons that Mrs Lim had = 4 x 1 u = 4 u
Before
Number of macarons that Natalie baked = 1 u
Number of macarons that Mrs Lim baked = 1 u + 445
4 u = 1 u + 445 - 166
4 u - 1 u = 279
3 u = 279
1 u = 279 ÷ 3 = 93
Number of macarons that Natalie baked
= 1 u
= 93
(b)
Number of macarons that Mrs Lim baked
= 1 u + 445
= 93 + 445
= 538
Answer(s): (a) 93; (b) 538
