6 pairs of shorts, for a

"s" dollars. A blazer costs 3 times as much, she bought one. The total was 139.50

6s + 3 (6s) = 139.50

6s + 18s = 139.50

25s = 139.50 Divide everything by 25,

s = 5.58, which is how much the shorts were. Now for the blazers;

It said they were three times the cost of shorts, if shorts are 5.58, it is 3*5.58.
