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.
