Answer:
y = 8 x
Explanation:
given data
costs = $56
rent a tent = 7 days
solution
As here two variables x and y represent proportional variation
so it is expressed as
k = [tex]\frac{y}{x}[/tex]
so y = k x ................1
and here linear equation represent a proportional variation
so we consider here number of days is x and cost to rent of tent is y
so relationship of this equation we get value of k that is
56 = 7 k
k = 8 days
so that equation is express as
y = 8 x
