#525# #"mL"# coffee

(I'm assuming that the "milk coffee" is different from the "coffee" itself.)

#"milk"/"milk coffee" = 2/5#

Let #x# be the volume of the milk coffee.

#2/5=(150"mL")/x#

#2x=5*150#

#2x=750#

#x=750/2#

#x=375#

So, there is #375# #"mL"# of milk coffee in the cup.

Add this to the volume of milk:

#375# #"mL"# milk coffee + #150# #"mL"# milk #= 525# #"mL"# coffee
