Varies directly means y = kx you solve for k and then use it in what you are trying to find.
cf = cost of fabric fp = fabric purchased. cf = k times fp or y = kx
10.00 = k(1 2/3) 1 2/3 is 5/3 10.00 = k(5/3) multiply both sides by 3/5 3/5(10.00) = k(5/3)(3/5) 6 = k
Now you start over. y = kx k is 6 so y = 6x
You are trying to find the cost which is y y = 6(4.5) 4 1/2 yards. y = $27.00
