Solve the problem.It is recommended that a woman who is pregnant should exercise such that her heart rate does not exceed 140 beats per minute. Use absolute value notation to write an expression that describes the difference between the heart rate achieved by each of the following pregnant women and the recommended maximum heart rate. Then evaluate that expression.(i) Abigail: 125 beats per minute(ii) Mathilda: 141 beats per minute
A. (i) Abigail: 
= 15
(ii) Mathilda: 
= 1
B. (i) Abigail: 
= -15
(ii) Mathilda: 
= -1
C. (i) Abigail: 125 - 140 = -15
(i) Mathilda: 141 - 140 = 1
D. (i) Abigail: 
= 265
(ii) Mathilda: 
= 281
