8.50x+100=308.25
subtract 100 from both sides
8.5x = 208.25
divide 8.5 from both sides
x= 24.5 hours worked
I = PRT...and since we are looking for r.....I / PT = R
I / PT = R
I = 510
P = 3000
T = 4
510 / (3000 * 4) =
510 / 12,000 =
0.0425 .....multiply by 100 to get the percent
4.25% <==
This question isn't phrased correctly, but I will assume it's asking about common denominators with fractions.
