What is the constant of proportionality for Nina's pet sitting service if she charges $34.50 for 6 days?

• $5.50

• $7.00

• $6.50

• $5.75

What is the equation relating the cost of pet sitting (C) to the number of days (D) if the constant of proportionality is $5.75?

• C = 5.75 * D

• C = D / 5.75

• C = 5.75 / D
