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. Use slope intercept form. Please help!!!!
This is the concept of algebra, we solve the question as follows: The cost of renting a camping tent is y The number of days is x cost is proportional to number of days, thus: yαx y=kx where k is the constant of proportionality. If y=$56 when x=7 days, then: 56=7k hence: k=56/7=8 therefore: y=kx will be: y=8x the equation in slope intercept form which is y=mx+c is y=8x. In our case c=0 because there was no initial payments required to rent apart from the daily charges.
