Question

Item 6

The cost y (in dollars) to rent a camping tent is proportional to the number xx 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.

Answer 1

y=kx, k is not equal to 0
when y=56, x=7, 56=7k
k=8
so the equation is y=8x
