Question

Can someone help me with this question?

2. A newspaper started an online version of its paper 14 years ago. In a recent presentation to stockholders, the lead marketing executive states that the revenues for online ads have more than doubled that of the revenues for printed ads since starting the online version of the paper. Use the graph below to justify the lead executive’s statement and to determine the approximate year that the two ad revenues were equal.

Answer 1

Here is the graph

Answer 2

@perl @amistre64 @abb0t Can you help me?

Answer 3

@Nnesha ? Can you help me?

Answer 4

@mathmate can you help me?

Answer 5

might want to define what "more than doubled" means.

Answer 6

Hm, that is a part of the question I don't understand. @amistre64 I guess it means it has doubled so much since it started, but other than that. I do not know.

Answer 7

the mathical statement to me seems to be:

online > 2(print)

we can see by the graph that print at year 14 is not greater than 2, correct?

Answer 8

Yeah. :)

Answer 9

the amount of online revenue is more than 2times the print revenue is how im reading it

we also see that online is bigger than 4

print < 2 < 2(2) < online

would seem to me to lend support to the statment

Answer 10

Yeah. @amistre64

Answer 11

Well, I have to 'Use the graph below to justify the lead executive’s statement and to determine the approximate year that the two ad revenues were equal.' What would that be? @amistre64

Answer 12

*Use the graph below to justify the lead executives statement and to determine the approximate year that the two ad revenues were equal.

Answer 13

we already processed the first part.

we can assume print to be equal to or less than 2

doubling it gives us an amount less than or equal to 4.

the online revenue is bigger than 4, therefore it is bigger than double the print.

Answer 14

when 2 things are equal, they have something in common, a common point of intersection.

when do the lines on the graphs intersect?

Answer 15

They intersect at about (8,2) @amistre64

Answer 16

so about the 8th year they are about equal.

id say that the intersection is between 6 and 8, so about the 7th year is a good approx for it.

Answer 17

Okay :) @amistre64 I was thinking about saying it, but I didn't know if I was right or not.

Answer 18

i spose it depends on who is grading it as to its correctness. its asking about approximations and not exacts so there should be enough wiggle room

Answer 19

Okay, thank you for helping me, and I'll give you a medal. :D
