The senior class had a car wash to raise money for the senior trip. It cost them $35 for supplies. They washed 75 cars and charged $6 for each car. Which of the following expressions represents the money they raised for their trip? A. $35 + 75 • $6 B. $35 - 75 • $6 C. 75 • $6 - $35 D. 75 - $35 • $6

The expressions that represents the money they raised for their trip is : C. 75 • $6 - $35.

Expression= 75 • $6 - $35

Where:

75 represent  the number of car that was washed

$6 represent the amount they charged

$35 represent supplies

The money raise can be calculated as:

Amount raised=75 • $6 - $35

Amount raised=$450-$35

Amount raised=$415

Inconclusion the expressions that represents the money they raised for their trip is : C. 75 • $6 - $35.

C. 75 • $6 - $35

Step-by-step explanation:

First, 75 times 6 needs to be in the expression to represent how much they raised from washing the 75 cars.

Then, 35 has to be subtracted because that was the cost of the supplies:

So, C is correct, 75 • $6 - $35

1; 35 is the ratio

step-by-step explanation:

"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).
