35 of her money and Japheth spent
23 of his money, they each had an equal amount of money left. How much money did they spend altogether?

Min |
Japheth |
Total |
Before |
5 u |
3x2 = 6 u |
$77 |
Change |
- 3 u |
- 2x2 = - 4 u |
|
After |
2 u |
1x2 = 2 u |
|
The amount that Min and Japheth each had in the end is the same. Make the amount that each had in the end the same. LCM of 2 and 1 is 2.
Total amount that Min and Japheth had at first
= 5 u + 6 u
= 11 u
11 u = 77
1 u = 77 ÷ 11 = 7
Total amount that Min and Japheth spent
= 3 u + 4 u
= 7 u
= 7 x 7
= $49
Answer(s): $49
