r = 255
r = R-2RF/W
R = 1,750
F = 63.2
W = 148
Now, we need to plug the values in to substitute the variables with real numbers.
r = 1750-2(1750 x 63.2)/148
First, solve for the parentheses.
r = 1750-2(110600)/148
Second, multiply by 2.
r = 1750-221200/148
Next, divide by 148.
r = 1750 - 1494.594
Then, we subtract.
r = 255.406
Lastly, we round it to the nearest whole number.
r = 255
