Step-by-step explanation:

As given

Ruby has a monthly salary of $1,800 and also earns 6% commission on her sales.

If Ruby had $37,000 in sales last month .

6% is written in the decimal form

= 0.06

Equation becomes

Total earnings for the month = Monthly salary + 0.06 × Sales last month

Put all the values in the above

                                               = 1800 + 0.06 × 37000

                                               = 1800 +  2220

                                               = $ 4020

Therefore the  total earnings of Ruby for the month is $4020 .

Option (d) is correct .
