Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction

revenue=$2000
therefore the labor cost as a percentage of Revenue is ($160/$2000) x 100
which equals 8%
