Step-by-step explanation:
Answer:
They cost the same amount
Step-by-step explanation:
Given
Lin:
where x = 14
Max:
for 14 days
Required
Which is less expensive?
Max charges has been given from the question as; $120 for 14 days.
To determine Lin's, we simply substitute 14 for x in 



The above result of y shows that Max charges for 14 days is also $120.
<em>Hence, they (Lin and Max) cost the same because they both equal to $120 for 14 days</em>
Since her base amount is 1200, we have 1200+<number>=<number>. Since she gets 35 dollars for every phone, if the number of phones she sells is x, we have 1200+35*x=the total amount of money in a month =4000 . Subtracting 1200 from both sides, we get 2800=35*x and by dividing both sides by 35 we get x=80
4y+12=7-5y add 5y to both sides
9y+12=7 subtract 12 from both sides
9y=-5 divide both sides by 9
y=-5/9
