Question

A horse's body temperature `T` is considered to be normal if it is within least 0.9 F of 99.9°F. What is the range of normal body temperatures for a horse?

Answer 1

`R: 99< T < 100.8`

Explanation:

A horse's body temperature is normal if it is 0.9°F within its normal body temperature of 99.9°F.

This means the lowest possible normal body temperature for a horse is

`99.9°F-0.9°F=99°F`

The highest possible normal body temperature for a horse is

`99.9°F+0.9°F=100.8°F`

I'm assuming the range in this context does not relate to the maximum minus the minimum (100.8°F-99°F=1.8°F), but in an algebraic sense.

Knowing the lowest normal temp. is 99°F and highest possible normal temp. is 100.8°F, then we can conclude for the range `R` and temperature in Fahrenheit `T`

`R: 99< T < 100.8`

I hope this helps!
