For this case we must find the cost of the bench, then:
Let "x" be the variable that represents the cost of the garden table.
Let "y" be the variable that represents the cost of the bench
If both cost $ 607 we have:
(1)
Now if the garden table costs $ 43 less than the bench then:
(2)
Thus, we have a system of two equations with two unknowns;
Substituting (2) in (1):

So, the bench costs $ 325
Answer:
$ 325
