Answer:

Step-by-step explanation:

Start : 268 + 212 = 480

End: 351 + 99 = 450

Start:

Percentage with resistance: 268/480 = 0.56 = 56%

Percentage without resistance: 212/480 = 0.44 = 44%

End:

Percentage with resistance: 351/450 = 0.78 = 78%

Percentage without resistance: 99/450 = 0.22 = 22%

Hope this helps!
