Question

Part A: Max rented a motorbike at $465 for 5 days. If he rents the same motorbike for a week, he has to pay a total rent of $625.

Write an equation in the standard form to represent the total rent (y) that Max has to pay for renting the motorbike for x days. (4 points)

Part B: Write the equation obtained in Part A using function notation. (2 points)

Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals. (4 points)

Answer 2

part A: y=65+80(x) plug in 5. 65+80(5)
y=65+400.
y=465.
when he rents the bike for five days, he pays 465. so if he rents it for a week he would be renting it for7 days (x)days. so y=65+80(7)
65+560.
y=625.

Answer 3

Now find the slope.

Answer 4

A.625-465=$160
he has to pay for 2 days=160 $
rent paid for 1 day=260/2=$80
amount paid for 5days=8*5=$400
But he paid $465
Difference 465-400=$65
so every one has to pay $65+rent for the no. of days
total rent for x days y=65+80 x (dollars)
B.
f(x)=65+80 x

Answer 5

how do i describe the steps ? for part c
