Ariadne has a shop selling hats of two different colors, red and green. Her sales from red hats were $400 in a particular month, half the total amount she earned from selling green hats. Calculate the total amount she made in two months if in the second month her sales were 3/4 of the total sales of the first month.
Since the total sales of red hats were half that of green hats in the first month, she made 2*$400=$<<2*400=800>>800 from green hats.
Her total sales in the first month are $800+$400=$<<800+400=1200>>1200.
In the second month, she made 3/4*1200=$<<3/4*1200=900>>900.
The total amount of money Ariadne made from two months of sales is $1200+$900=$<<1200+900=2100>>2100.
