Help! MEDAL :D The sales totals at Linda's food store have increased exponentially over the months. Which of these best shows the sales in the first three months? $1200 in the first month, $1260 in the second month, and $1323 in the third month $1200 in the first month, $1250 in the second month, $1300 in the third month $1200 in the first month, $1272 in the second month, $1344 in the third month $1200 in the first month, $1285 in the second month, $1370 in the third month

B?

OpenStudy (anonymous):

B has increased linearly.

OpenStudy (anonymous):

so is it correct?

OpenStudy (anonymous):

The question asks for expontential increase, and linear increase is not the same.

OpenStudy (anonymous):

$1200 in the first month, $1285 in the second month, $1370.96 in the third month for this one, 1285/1200 = 1.0708, but 1370.96 /1285 = 1.06689

OpenStudy (anonymous):

You see in B, the increase is 50 per month. C increases 72 per month D increases 85 per month A does not have the same pattern as the other 3.

OpenStudy (anonymous):

So B,C,D are increasing linearly every month, but for A you see an increase of 60 and then 63, which is what would resemble expontential increase the most... D:

OpenStudy (anonymous):

The "increase" increases every month in A, if you get it??
