Question

Part A: Abe rented a bike at $36 for 5 days. If he rents the same bike for 8 days, he has to pay a total rent of $48.Write an equation in the standard form to represent the total rent (y) that Abe has to pay for renting the bike for x days. Part B: Write the equation obtained in Part A using function notation. Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.

Answer 1

We need to find an equation that represents the total rent, we proceed

`y=\frac{36\text{dollars}}{5\text{day}}x`

simplifying

`y=7.2x`

We use the fact that the cost of 5 days is equal to 36 dollars, which helped us find the rate of money per day. If x is the number of days then the price to pay for renting "x" days is the product of "x" by the rate
