Ali's heart rate is 135 times per minute.
Step-by-step explanation:

It is provided that Ben's heart beats 18 times per minute more than Ali.

Thus, Ali's heart rate is 135 times per minute.
142=120% of x
120% of x= 1.2x
142=1.2x
142/1.2 = 1.2x/1.2
x= 118.33
The unknown number should be 118.33, rounded to 118 or so.
