The vertex is (h,k) (2,-6) the axis of symmetry is x=2
Let's say a stands for apples and p for pears
We know that

And

In order to know what the cost of an "a" is we have to put the value of the p in the second equation, which means



And

The price of per kilo for apples is 1.80
since they both end with 5 divide each number by 5
4415 = 883
22245/5 = 4449
there is no number that can go into 883 evenly
so the lowest term
would be 883/4449
