An architect designs a division of townhouses. He uses the table to determine the number of parking spaces needed for the residents.


Number of Townhouses Number of Parking Spaces
1
3

10
30

100
300

1,000
3,000


The architect knows that this relationship is proportional. So, he needs to offer _[blank 1]_ parking space(s) per townhouse. This can be represented by the ordered pair _[blank 2]_.

Select two answers: one for blank 1 and one for blank 2.

To determine the number of parking spaces needed per townhouse, we can analyze the relationship from the table:

  • For every townhouse, there are 3 parking spaces. This means that 3 parking spaces are needed per townhouse.

Thus, the correct response for blank 1 is 3.

For blank 2, the ordered pair that represents this relationship (where the first number is the number of townhouses and the second number is the number of parking spaces) is (1, 3), since when there is 1 townhouse, there are 3 parking spaces needed.

So the answers are:

blank 1: 3
blank 2: (1, 3)
