david, a cook, is heating oil to make french fries. he uses this thermometer to check the temperature of the oil. what temperature is the oil? 315°f 325°f 340°f 350°f

Answer

Explanation:

Step1: Identify scale intervals

The thermometer has intervals of 25°F between major - marks (e.g., 250°F, 300°F, 350°F). Between two major - marks, there are 5 smaller intervals. So each small interval represents $\frac{25}{5}=5$°F.

Step2: Determine the reading

The pointer is 3 small intervals past 300°F. Since each small interval is 5°F, the additional temperature is $3\times5 = 15$°F. So the temperature is $300 + 15=315$°F.

Answer:

315°F
