Answer:

a) Lower limit range = 119.7 ≈ 120

b) Upper limit range = 136.8 ≈ 137

Step-by-step explanation:

Given:

a) Lower limit range = $\frac{\textup{7}}{\textup{10}}\times(220-\textup{Age})$

Therefore,

For the given person of age 43 years old

substituting the value of age in the above equation, we get

Lower limit range = $\frac{\textup{7}}{\textup{10}}\times(220-\textup{49})$

or

Lower limit range = 119.7 ≈ 120 beats per minute

b) The upper limit range = $\frac{\textup{4}}{\textup{5}}\times(220-\textup{Age})$

Therefore,

For the given person of age 43 years old

substituting the value of age in the above equation, we get

Upper limit range = $\frac{\textup{4}}{\textup{5}}\times(220-\textup{49})$

or

Upper limit range = $\frac{\textup{4}}{\textup{5}}\times(220-\textup{49})$

or

Upper limit range = 136.8 ≈ 137 beats per minute

So the first two line segments added together equals the full line segment. So, 8y + 5 + 7y = 13y + 25

15y + 5 = 13y + 25

2y = 20

y = 10
