Samantha was earning $6.35 per hour in her old job. she changed jobs, and got a raise, to $8.78 per hour. which equation can you use to find r, the amount her hourly wage increased? a) r/6.35=8.78,. b) 6.35r= 8.78,. c) 8.78 + r = 6.35,. d) 6.35 + r = 8.78

I believe the answer would be D because 8.78 subtracted by 6.35 would give us art so if you were to know are you could check the answer by doing 6.35 + R equals 8.78 but since you're not doing subtraction it would be the most likely answer

Hope this helps!!!
