Answer:
$150
Explanation:
A garden table and a bench together will cost $600. The actual values of the garden table and the bend are not given, but we know that the cost of a garden table will cost three times more than the bench.
Let
= the cost of the bench.
Again, since the cost of the garden table is three times the cost of the bench (
), we can represent the garden table as three times
(
). These two terms will equal $600 when added, so let's formulate an equation:

Combine like terms:

Divide both sides of the equation by the coefficient of
, which is
:

_
Check your work by substituting
into the original equation:



Our answer is correct!
