Whenever you're interested in computing the (absolute) difference between two values of a certain variable, you have to subtract the final value and the initial value. This is often written as delta:
So, in this case, the final temperature is -30°F. The initial temperature is 115°F. So, the variation is
A negative delta indicates that the value decreased, which is our case.
Answer:
$100
Step-by-step explanation:
Let C be the cost for 150 minutes of play time.
We have been given that Quinn is playing video games at a virtual reality game room. The game room charges 20 dollars for every 30 minutes of play time.
We will use proportions to find the cost for 150 minutes of play time as proportions states that two fractions are similar.
Upon substituting the given value we will get,
Upon cross multiplying our equation we will get,
Upon dividing both sides of equation by 30 we will get,
Therefore, Quinn need $100 to pay for 150 minutes of play time.
