y=−2.25x
y equals negative 2.25 x

y=x+2.25
y equals x plus 2.25

y=2.25x
y equals 2.25 x

y=x−2.25

Answer 1

The relationship between the input (boxes) and the output (cost) can be represented by the equation that describes how the cost increases with the number of boxes. From the given table, we can see that for each box added, the cost increases by $2.25.

This can be expressed algebraically as:

y = 2.25x

where y represents the cost and x represents the number of boxes.

So the correct response is:

y = 2.25x
