SOLUTION

GIVEN

Leonardo read that his reptile food should be given at a temperature of 72.5°F.

He keeps the food in the freezer at –4°F.

He has found that if he sets the food on his reptile’s hot rock, the temperature rises 8.5 degrees each hour.

TO DETERMINE

The time it will take for the reptile food to reach 72.5°F

EVALUATION

Let t hours is required for the reptile food to reach 72.5°F

Here it is given that Leonardo keeps the food in the freezer at –4°F

Now he sets the food on his reptile’s hot rock, the temperature rises 8.5 degrees each hour.

So after t hours the temperature will be

= ( - 4 + 8.5t )°F

Now Leonardo read that his reptile food should be given at a temperature of 72.5°F.

So by the given condition

$\sf{ - 4 + 8.5t = 72.5}$

$\sf{ \implies \: 8.5t = 76.5}$

$\sf{ \implies \: t = 9}$

So 9 hours is required for the reptile food to reach 72.5°F
