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.
3s
3(5.58)
16.74
The blazer cost 16.74
You need to do like this:

Plug the numbers into the formula:

because they said
<u>is </u>90 and
<u>of</u> what?
Multiply diagnally: 100 × 90 = 9000 ÷ 82 ≈
109.76
i don't really sure it was completly correct but hoped it helps:)
