Comparing Anna
and Natalie at first |
$98 more |
|
| Before |
7x4 =
28 u |
7x3 =
21 u |
| Change |
- 4x4 =
- 16 u |
- 6x3 =
- 18 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Anna
and Natalie in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Anna had in the end is repeated. Make the amount that Anna had in the end the same. LCM of 4 and 3 is 12.
Amount that Natalie had less than Anna
= 28 u - 21 u
= 7 u
7 u = 98
1 u = 98 ÷ 7 = 14
Amount that Anna had at first
= 28 u
= 28 x 14
= $392
Answer(s): $392
