Answer

Explanation:

Step1: Calculate cable used for first - type locations

$2\times100 = 200$

Step2: Calculate cable used for second - type locations

$6\times50=300$

Step3: Calculate cable used for third - type locations

$4\times35 = 140$

Step4: Calculate total cable used

$200 + 300+140=640$

Step5: Calculate cable left for last 3 locations

$1000 - 640=360$
