27 of her money and Ken spent
12 of his money, they each had an equal amount of money left. How much money did they spend altogether?

Emily |
Ken |
Total |
Before |
7 u |
2x5 = 10 u |
$170 |
Change |
- 2 u |
- 1x5 = - 5 u |
|
After |
5 u |
1x5 = 5 u |
|
The amount that Emily and Ken each had in the end is the same. Make the amount that each had in the end the same. LCM of 5 and 1 is 5.
Total amount that Emily and Ken had at first
= 7 u + 10 u
= 17 u
17 u = 170
1 u = 170 ÷ 17 = 10
Total amount that Emily and Ken spent
= 2 u + 5 u
= 7 u
= 7 x 10
= $70
Answer(s): $70
