Item 6 The cost y (in dollars) to rent a camping tent is proportional to the number x of days that the tent is rented. It costs $56 to rent a tent for 7 days. Write an equation that represents the cost to rent a camping tent for x days

Respuesta :

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
