Answer:
$800
Step-by-step explanation:
Kevin earns a base pay = $325 /week
He also make some extra earning in the form of commission. Let this extra earning be “$X”
Thus, Base pay + Extra earning through commission = $1125 -------------Equation (A)
Substituting the values in equation A, we get –
$325 + $X = $1125
$X = $1125 - $325
= $ 800
