Total |
Before |
7 u |
4x4 = 16 u |
$69 |
Change |
- 3 u |
- 3x4 = - 12 u |
|
After |
4 u |
1x4 = 4 u |

The amount that Jane and Howard each had in the end is the same. Make the amount that each had in the end the same. LCM of 4 and 1 is 4.
Total amount that Jane and Howard had at first
= 7 u + 16 u
= 23 u
23 u = 69
1 u = 69 ÷ 23 = 3
Total amount that Jane and Howard spent
= 3 u + 12 u
= 15 u
= 15 x 3
= $45
Answer(s): $45
