Item 4 A movie theater sells 70 regular tickets and 40 matinee tickets in one day. Each regular ticket costs $15 and each matinee ticket costs $12. What is the total amount of ticket sales on this day?

The total amount of ticket sales on this day is $1530.

Step-by-step explanation:

From the information given, the total amount of ticket sales would be equal to the result of multiplying the number of regular tickets sold for its price plus the number of matinee tickets sold for its price, which would be:

Ticket sales=15R+12M, where

R= number of regular tickets sold= 70

M= number of matinee tickets sold= 40

Now, you can replace these values on the formula to find the total amount of ticket sales on this day:

Ticket sales=15(70)+12(40)

Ticket sales=1050+480

Ticket sales=1530

According to this, the answer is that the total amount of ticket sales on this day is $1530.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
