Answer:
c=7/3p
Step-by-step explanation:
Let's find the constant of proportionality.
in the proportional relationship between p, the number of hours parked, and c, the cost in dollars, one constant of proportionality is the cost per hour. It is the number we multiply by the number of hours to get the total cost.
p×?=c
px?=c
?=
= 7/3
the constant of proportionality is 7/3 this means we can multiply 7/3 by the numbers of hours to get the total cost
Now, let's write the equation: total cost
total cost=cost per hour×number of hours
