Riordan had $124 more than Zane. After each of them bought a different sweater from a shop. Riordan and Zane were left with equal amount of money. Given that Riordan's sweater cost 3 times as much as Zane's sweater, how much did Riordan's sweater cost?

Riordan |
Zane |
More |
Before |
1 u + 3 p |
1 u + 1 p |
$124 |
Change |
- 3 p |
- 1 p |
|
After |
1 u |
1 u |
|
The amount that Riordan and Zane had in the end is the same.
3 p - 1 p = 124
2 p = 124
1 p = 124 ÷ 2 = 62
Cost of Riordan's sweater
= 3 p
= 3 x 62
= $186
Answer(s): $186
