Mrs Heng gave Victoria and Natalie some money each on Tuesday. On Wednesday, Victoria gave

$56 |
Change 1 |

+ 1 u |

After 1 |
4 u |
4 p |
$56 |
Before 2 |
$44 - 1 p |
4 p |
$56 |
Change 2 |

After 2 |
$44 |
3 p ($12) |
$56 |
Amount that Natalie had in the end = 3 p
3 p = 12
1 p = 12 ÷ 3 = 4
Working backwards.
Amount that Victoria had after giving to Natalie on Wednesday
= 44 - 1 p
= 44 - 4
= $40
4 u = 40
1 u = 40 ÷ 4 = 10
Amount that Victoria had at first
= 5 u
= 5 x 10
= $50
Total amount that Victoria and Natalie had
= 44 + 12
= $56
Amount that Natalie had at first
= 56 - 50
= $6
Amount that Victoria had more than Natalie
= 50 - 6
= $44
Answer(s): $44
