If you're asking what is the unit rate of 3 1/2 in 1 1/4 things then it is 7/2 * 4/5 which is 14/5 or 2 4/5
I couldn't find the constant of proportionality ( probably 25). 1/4 (25%) of $29 is $1.16.
$29+$1.16 = $30.16
A pair of $29 jeans would cost $30.16.
The distance between points a and b is about 18.03. The distance between points b and c is about 18.38. The distance between points c and a is 5. To graph it, you just put the points on the graph, i can't do that on here, but, that is the simpliest part.
