| Change |
- 1 blouse |
- 1 blouse |

| After |
7 u |
1 u |
6 u |
Since Tommy and Ethan each bought an identical blouse, the difference in amount that they had at first and in the end remains the same.
6 u = 30
1 u = 30 ÷ 6 = 5
Amount that Tommy had left
= 7 u
= 7 x 5
= $35
Cost of the blouse
= 61 - 35
= $26
Answer(s): $26
