Answer:
($4.00/x)+($4.50/y)
Step-by-step explanation:
we know that
Apples cost 80 cents for x apples
so
One apple cost $0.80/x
Oranges cost 75 cents for y oranges
so
One orange cost $0.75/y
Find the cost of 5 apples and 6 oranges
Multiply the number of apples by the cost of one apple and multiply the number of oranges by the cost of one orange
so
5($0.80/x)+6($0.75/y)=($4.00/x)+($4.50/y)
7.6x = 64
7.6/7.6
Therfore, x = 64/7.16
x = 8.938
