Kimberly and Luis went shopping with a total of $153. After Kimberly spent
25 of her money and Luis spent
34 of his money, they each had an equal amount of money left. How much money did they spend altogether?
|
Kimberly |
Luis |
Total |
Before |
5 u |
4x3 = 12 u |
$153 |
Change |
- 2 u |
- 3x3 = - 9 u |
|
After |
3 u |
1x3 = 3 u |
|
The amount that Kimberly and Luis 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 Kimberly and Luis had at first
= 5 u + 12 u
= 17 u
17 u = 153
1 u = 153 ÷ 17 = 9
Total amount that Kimberly and Luis spent
= 2 u + 9 u
= 11 u
= 11 x 9
= $99
Answer(s): $99
