Same question as the previous one but forgot to show the answer choices

C

Step-by-step explanation:

x apples cost 80

1 apple  costs 80/x

5 apples costs 80*5/x = 400/x

The same calculation works for the oranges.

y oranges cost 75

1 orange = 75/y

6 oranges = 75*6/y

6 oranges = 450/y

The total cost is 450/y + 400/x which is C

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.
