Q:

3. You complain that the hot tub in your hotel suite is not hot enough. The hotel tells you that they will increase the temperature by 10 degrees each hour. If the current temperature of the hot tub is 75º F, what will be the temperature of the hot tub after 3 hours?HELP PLEASE!

Accepted Solution

A:
Answer:   105 °FStep-by-step explanation:Add 10 °F to the temperature for each of the 3 hours:   75 °F + 10 °F + 10 °F + 10 °F = 105 °F_____Of course, multiplication was invented to make repeated addition easier. Multiplying the increase each hour by the number of hours gives the total increase:   75 °F + (3 h)(10 °F/h) = 75 °F +30 °F = 105 °FThe temperature of the hot tub after 3 hours will be 105 °F.
