Leanne runs on the treadmill and rides the exercise bike at the gym to stay in shape. She burns 15 calories per minute on the treadmill and 9 calories per minute on the bike. She wants to ride the bike 2.5 times as long as she runs on the treadmill and burn a total of 580
calories. The system of equations below can be used to find the number of minutes, t, she should run on the treadmill and the number of
minutes, b, she should ride the bike.
| 151 +95 - 580
b-2.51
According to this system of equations, can Leanne meet both her goals?
A. No, she cannot run on the treadmill for a fractional number of minutes.
OB. Yes, she can run on the treadmill for 15 minutes 28 seconds.
C. No, she cannot ride the exercise bike a negative number of minutes.
D. Yes, she can ride the exercise bike for 15 minutes 28 seconds.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
