Problema Solution
Two yards of fabric cost $13, and 5 yards of fabric cost $32.50. Which equation
relates the cost of the fabric c to its length ?
c = 2.6 c = 6.5 c
Answer provided by our tutors
let
c = the cost of the fabric
l = the length of the fabric
c : l = 13 : 2
c : l = 32.50 : 5
c : l = 6.5
c = 6.5l
