Answer:  $ 532
Step-by-step explanation:
Given: Ramona works in a clothing store where she earns a base salary of $140 per day plus 14% of her daily sales. 
She sold $600 in clothing on Saturday and $1200 in clothing on Sunday. 
To find : Earning in two days.
Total sales she did in 2 days = $600+$1200 = $1800
Then, her total earning for 2 days = 2 x( Base salary)+ 14% of (Total sales) 
= 2 x ($140) + (0.14) ($1800)
= $(280+252)
= $ 532
Hence, she earned  $ 532 over the 2 days.
