Answer:

B) Let x = yesterday's body temperature

x + 2.5° = 100.7 °F

x = 98.2 °F

Explanation:

We want to determine Dud's body temperature yesterday. Therefore, the unknown variable is:

  • Let x = yesterday's body temperature

If Dud's body temperature today is 2.5° higher than yesterday's body temperature, then his body temperature today is the sum of yesterday's body temperature and the increase:

  • x + 2.5° = 100.7 °F

To solve the equation, subtract 2.5° from both sides of the equation:

  • x + 2.5° - 2.5° = 100.7 °F - 2.5°
  • x = 98.2 °F

Therefore, Dud's body temperature yesterday was 98.2 °F.
