Fred and Wendy had equal amount of money. Fred spent
12 of his money on a coat while Wendy spent
34 of her money on a jacket. Given that Wendy spent $7 more than Fred, how much did Fred have at first?

Fred |
Wendy |
Before |
2x2 = 4 u |
4x1 = 4 u |
Change |
- 1x2 = - 2 u |
- 3x1 = - 3 u |
After |
1x2 = 2 u |
1x1 = 1 u |
The amount that Fred and Wendy had at first is the same. Make the amount that Fred and Wendy had at first the same. LCM of 2 and 4 is 4.
Amount that Wendy spent more than Fred
= 3 u - 2 u
= 1 u
1 u = 7
Amount that Fred had at first
= 4 u
= 4 x 7
= $28
Answer(s): $28
