8.75-4.85= 3.90= cost of 6 bananas
3.9/6=0.65= cost of one banana
.65*4=2.60= cost of 4 bananas
4.85-2.60= 2.25= cost of 3 apples
2.25/3=.75= cost of an apple
$ 0 . 75

8.75-4.85= 3.90= $ of 6 bananas
3.9/6=0.65= $ of 1 banana
.65*4=2.60=  $ of 4 bananas
4.85-2.60= 2.25= $ of 3 apples
2.25/3 = $ of an apple
