Step-by-step explanation:
The total earnings are the amount of commission added to a monthly salary. We already know the monthly salary but still have to find out the amount of commission. Ruby gets a 6% commission of her sales, which is $37,000 of that month. The amount of commission she get will be: 6% * $37,000= $2220
The total earnings it will be:
salary + commision=
$1,800+ $2,220 = $4,020
