Answer:
102 ≤ heart rate ≤ 183.6
Step-by-step explanation:
... lower limit ≤ heart rate ≤ upper limit
Put 16 where "a" is and do the arithmetic.
... lower limit = 0.5(220 -16) = 102
... upper limit = 0.9(220 -16) = 183.6
Then the inequality is ...
... 102 ≤ heart rate ≤ 183.6

<em>Comment on the problem</em>
There is nothing to "solve" here. One only needs to evaluate the limits.
Yes 2/5 and 4/10 are equivalent fractions. This is because you are able to multiple both numbers in 2/5 by 2 and get 4/10. In addition, you can divide both numbers in 4/10 by 2, therefore they’re equivalent.
