Answer 2

So do you know how to write an equation, yousuf?

Answer 3

i'm not very good at writing equations but I will try

Answer 4

So do you know what the constant could be for the equations?

Answer 5

would it be 20 and 8

Answer 6

No, those numbers are for PER LOAD

The other two numbers are a one time fee for any amount of load

Do you understand? :)

Answer 7

oh ok

Answer 8

i'm still confused though

Answer 9

So, for part a we can make two equations

Company A's equation is y = 20x + 8
Company B's equation is y = 24x + 4

Do you agree? :)

Answer 10

yes

Answer 11

Now for part b, do you know what to do?

Answer 12

i do the equation now right

Answer 13

you plug in 5 into both equations and see which company has a smaller amount for y :)

Answer 14

do it yourself, but post your work so I can make sure

I'll wait for you reply :)

Answer 15

ok i will

Answer 16

:)

Answer 17

im stuck on how place the 5 in the equation

Answer 18

y=20x+8
5 -5 am i doing it wrong?

Answer 19

yea

Answer 20

you replace x with 5

Answer 21

so
y = 20(5) + 8
y = 100 + 8
y = ?

Answer 22

ok i'm sorry but i'm really dumb and i have know idea what to do
but is y-=108

Answer 23

y=108

Answer 24

yes

Answer 25

now do it for the other equation :)

Answer 26

ok

Answer 27

is it 95

Answer 28

how did you get that?

Answer 29

by doing this
y=20(5)+8
5 -100
95

Answer 30

do you still need help with this?

Answer 31

i don't know what to do, i'm very confused

Answer 32

i don't know the steps for this problem

Answer 33

try this

y = 24(5) + 4

solve for y :)

Answer 34

is it 124

Answer 35

hold on I will help you with all parts k?

Answer 36

ok thx

Answer 37

why?

Answer 38

when I'm already helping..

Answer 39

and that's correct @safyousuff97

Answer 40

ok thats for part a right

Answer 41

so which company is cheaper for 5 loads?

Company A charges 108 for 5 loads
Company B charges 124 for 5 loads

Answer 42

this is for part b, we completed part a already :)

Answer 43

company a

Answer 44

correct

that's your answer for part b :)

Answer 45

Company A
$20 per load
$8 service
Company B
$24 per load
$4 service


PART A:
Let l be the number of loads

Company A = 20l + 8
Company B = 24l + 4


PART B:
Company A = 20*5 + 8
= $108
Company B = 24*5 + 4
= $124
Company A charges less


PART C:
Company A = 20*9 + 8
= $188
Company B = 24*9 + 4
= $220

220 - 188 = 32
You save $32.

Answer 46

and now do what we did for part b for part c

but instead of using 5, use 9
