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.

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 2

Do you have an idea on how to start?

Answer 3

no idea. i only know how to do part c

Answer 4

Ok, first we need to find the cost for 1 day

Answer 5

which i cant do without part a and b

Answer 6

wait, no

Answer 7

one day is 93, right

Answer 8

We need to find slope

Answer 9

oh ok give me a sec

Answer 10

but yes, 1 day is 93, wait, 1 day is the slope, duh

Answer 11

so we have 5, 465 and 7, 625

625 - 465/7 - 5
160/2
80/1

?????

Answer 12

oooh

Answer 13

now I'm confused...

Answer 14

@ankit042

Answer 15

it says write in standard for which is Ax + By = C, right?

Answer 16

465=5m+c
625=7m+c
now subtract two from one to get value of m

Answer 17

i am so confused

Answer 18

m will be the per day cost and c is upfront cost

Answer 19

what is c? is it b in y = mx + b

Answer 20

yeah I use y = mx+c notation

Answer 21

oh

Answer 22

To explain this let us assume we have this case where to rent a motor cycle you have to pay some upfront cost which is independent on number of day you hire the bike for (c)
and m is the rent for each day
so for x days one has to pay y dollars which can be represented as
y=mx+c

Answer 23

@sleepyjess still confused?

Answer 24

uuuuummmm yeah

Answer 25

i am supposed to write one equation to represent the total rent and x days
do i do
465 = 5m + b or 625 = 7m + b

Answer 26

using these equations you will find values of m and b then to represent it for x days you will say
y=mx+b ( replacing values for m and b)
