Use ratio and proportion:  


$29.50 is to 250 ft. as how much is to 40 ft.  

29.5 / 250 = x / 40  

x = 40(29.5) / 250  

x = 1180 / 250  

x = 4.72  

40 ft. would cost $4.72

Here's how you solve it!

250/2950 = 40/x

x(250/2950) = (40/x)x

250x/2950 = 40

2950(250x/2950) = (40)2950

250x = 118,000

250x/250 = 118,00/250

x = 472

The cost of 40 ft of cable is 472.


Hope this helps! <3
