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

82 is 90% of what number?

chubhunter [2.5K]

You need to do like this:
$\frac{no.}{100} = \frac{is}{of}$
Plug the numbers into the formula:
$\frac{82}{100} = \frac{90}{?}$ because they said is 90 and of what?
Multiply diagnally: 100 × 90 = 9000 ÷ 82 ≈ 109.76
i don't really sure it was completly correct but hoped it helps:)
