Can you add a picture if you can in order for me to solve this question.
'of' means multiply
half a dozen means 12/2=6
6 of one thing means 6 times x
plus means ad
half a dozen of another mean 6 times y
they are added
6x+6y
2 variables
it says 'of the other' so they are diferent
550+450-120+720=1,600
720/1,600*100%
=720/160%
=45%
therefore, 45% of new balance
