Final answer:
The constant of proportionality for renting a snowmobile at $37.50 for 5 hours is $7.50 per hour. The equation representing the relationship is y = 7.50x, where y is the total cost and x is the number of hours.
Step-by-step explanation:
The student has asked for the constant of proportionality when renting a snowmobile that costs $37.50 for 5 hours.
To find the constant of proportionality, we divide the total cost by the number of hours:
Constant of Proportionality = Total Cost / Number of Hours
Constant of Proportionality = $37.50 / 5 hours = $7.50 per hour
The constant of proportionality, which represents the cost per hour, is $7.50.
To write an equation representing this relationship where y is the total cost and x is the number of hours:
y = 7.50x
