25 of her money and Andy spent
56 of his money, they each had an equal amount of money left. How much money did they spend altogether?

Yen |
Andy |
Total |
Before |
5 u |
6x3 = 18 u |
$46 |
Change |
- 2 u |
- 5x3 = - 15 u |
|
After |
3 u |
1x3 = 3 u |

The amount that Yen and Andy each had in the end is the same. Make the amount that each had in the end the same. LCM of 3 and 1 is 3.
Total amount that Yen and Andy had at first
= 5 u + 18 u
= 23 u
23 u = 46
1 u = 46 ÷ 23 = 2
Total amount that Yen and Andy spent
= 2 u + 15 u
= 17 u
= 17 x 2
= $34
Answer(s): $34
